Two flute Metric Straight bit

Carbide Tipped

In choosing a straight bit for any application, always select one with the shortest cutting edges and the shortest overall length that will reach the required depth. Excessive length intensifies deflection and vibration, which degrade cut quality and lead to tool breakage.

Use a two-flute bit where fine finish is paramount. Two flutes balance the bit, eliminating vibration that degrades the cut finish.

Two cuts per revolution yield a smooth surface, but feed rate is slightly reduced.

This router bit has a 12,7 mm shank (shaft) that will fit most large routers. Please ensure that you select a router bit with a shank (shaft) size that will fit into your router collet.

 

PRO-TECH router bits are manufactured in Taiwan.

General safety suggestions:

It is advisable to always have the following items nearby and in a good condition

  • Eye protection clean and scratch free
  • Hearing protection quality earmuffs
  • Dust masks discard old and dirty masks
  • Gloves for easy handling of material and hand protection

To use router bits safely (and to get the best results from your router), the router bits need to be installed properly into the router's collet. Improper installation of your bits can cause excessive chatter and could increase the likelihood that the bits will break when in use. 

Clean and sharp

First of all, before beginning any routing operation, check your bits to make sure that they are clean, relatively free of pitch, and most of all, sharp. If the bit is dull, chipped, is excessively burned or has any other defect, it should be sharpened or replaced before use. 

Correct collet and collet nut fit

Most router collets have a recess (groove) that needs to click into a circlip that resides inside the collet nut. Failing to ensure that the collet 'clicked' into the collet nut will cause you to struggle to remove the router bit after tightening. This could cause the collet to break or be removed by a technical repair centre.

 

Correct fit inside the collet

When installing the bit into the collet, do not tighten the collet with the bit 'seated.' Instead, insert the bit until the shank (bit shaft) reaches the bottom of the collet, then ease it out about 2 mm before tightening the collet.

When the bit is tightened, there should be no less than  2/3 's of the length of the shank in the collet. If your bit has a shank that is too short, then the bit should be replaced. 

 

Safety gear

There are a few other safety measures to keep in mind whenever you use your router. First of all, remember to always wear appropriate safety gear as indicated above.

Correct speed setting

Second, be sure to set your router to the proper speed for your router bit. Setting your router to an incorrect speed will not only affect the router's performance, but also can cause the bit to break much more easily and even cause bodily harm. The speed at which a router bit turns can be important. The typical router runs at about 22,000 rpm, which is fine for most bits. But as the diameter of the bit increases, you ll want to slow things down.

Also, before beginning any routing operation, be certain that you give the router's motor time to come up to full speed for the chosen setting. Beginning to cut before the bit is at full speed can give less than desired results. 

Observe the following at all times

  • Wear a protective face shield or Safety Glasses to prevent eye and face injury.
  • Wear ear plugs or ear muffs to protect your hearing.
  • Use a respirator or dust mask to give protection from dust particles. Wood dust may remain in the air for hours after using power tools.
  • Always read and follow router operator's manual instructions.
  • Make sure that router rpm's and the bit selected match.
  • Dress properly. Wear short sleeves, no loose fitting clothes, proper footwear and no jewellery. Tie back long hair.
  • Always be sure the router is unplugged before replacing bits and that the switch is off before connecting the router.
  • Be sure the router bit has completing stopped spinning before sitting the router down.
  • Be sure bits, clamps and attachments are secure before starting up.
  • Keep children, pets and visitors at a safe distance.
  • Be especially cautious when working small pieces.
  • Keep hands and fingers away from revolving bits and cutters.
  • Do not operate routers in moist or wet areas.
  • Always grip tool tightly and be prepared at start-up to resist the motor torque.
  • When using a router table, make sure on/off switch is easily accessible.
  • Learn the sound of your router and shut it off at any unfamiliar sounds or irregularities.
    Never start the router with the bit in contact with the material.
  • Always feed in the proper direction, against the direction of bit rotation.
  • Maintain equipment. Replace worn parts, discard worn-out bits and check router periodically. Clean parts with appropriate solvents.
  • Don't operate a tool if you are tired or under the influence of medication, drugs, alcohol or while smoking.
  • Check wood for nails, screws or loose knots before routing.
  • Keep your mind on your work, avoid distractions, work at a comfortable pace and stop before you get tired.

Do a dry run

  • Place the router on the final work surface and test you cut by moving the router over the whole are to cut with THE ROUTER SWITCHED OFF
  • You do not want to waste an expensive piece of wood
  • You do not want to start all over
  • Never met anyone with spare fingers - SAFETY

Very good quality for the price!!!
Color: Onyx Black
This chair really shine for its performance. I was afraid it would be a scam. Lucky me, is a bang for the price! Quality is pretty good (for the price) the whole thing keeps it's structure firm. Considering I'm not precisely light( 5'11" @ 240 lbs) this chair holds my dad bod with no issue. Stability is great! Lumbar support has plenty of room for adjustment. The head support can be set an virtually any position your body might need. Being meshed makes it really comfy. I would say it looks neat. Not bad for a professional office, I mean it doesn't match those chairs above 1k but still a good looking chair. The only flaw: although arm rest supports can be adjusted up/down and front/back unfortunately you can't fold them back. This is not precisely an issue but I think it would be really nice having more room when needed. Oh, and the legs extension: it does its job very decently! In general: you won't regret purchasing this thing

Arm Rests are a big disappointment
Color: Onyx Black
2 weeks of use. The price seems fair for what you get. The mesh is a lower quality material and I could see it getting uncomfortable for more than a few hours sitting. It feels taut with limited cushion/give. The arm rests are a big let down. They are firm and slick so not pleasant for planting a pointy elbow into. The biggest drawback though is the many positions the arm rest can be set to. It has forward and backward adjustments and some odd angle-in/angle-out positions. The problem is that the slightest pressure on the arm rests and they move so you really cannot put your weight on them to get up or down or to readjust your posture. The result is you are afraid to touch them, and if you do, you get a loud clicking sound as the arm rest shifts away from your pressure until it hits its final position. This is jarring and frustrating. I would recommend they remove this adjustability or make it require a lever pull instead of adjust at about 5lbs of incidental pressure. If I keep the chair, I will be sending a screw up into the arm rest to lock it into place. Note that the up and down adjustment of the arm rests are fine as that requires a lever. The leg rest is good and works as expected. Lumbar support works well reclining and chair ergonomics are good.

Found a great chair
Color: Onyx Black
I'm really glad I looked around as long as I did, because this chair has been fantastic. It went together easily, all the ways it adjusts work great and are easy to figure out (even the back-tilt-lock thingy), and it's really comfortable even after a whole day in it. I am on the larger side, and haven't had a single creak out of the thing. It's very sturdy. The mesh of the seat and back are great here in the desert as well.

Has good height and back support
Color: Onyx Black
I am very happy with the chair. I did replace the wheels with new casters. Didn't even try the originals though they look sturdy because they appear to be wider than others that I have seen. The arms are a little fiddley and can move when you don't necessarily want them to. What more than makes up for those minor issues is the fact that it easily fits my long legs and has great back support. It is mesh so warmth is not an issue. I think the mesh helps with the comfort rather than being sunk into a pillow. As a bonus, there is a leg rest. I can get comfortable enough to take a nap or can watch a movie while reclined. It feels very sturdy while in that position. I weigh about 205. Happy with the chair and I would recommend it for those who have a need. Great value.

Very sturdy and comfortable for the price.
Color: Onyx Black
The chair is easy to put together and very comfortable. I like that you can adjust how easy it reclines back, and absolutely love the reclined position with the foot rest up. Kinda feels like zero gravity. The foot rest is best when you’re in a reclined position. If you have it up while in an upright position, it’s a little awkward because it’s not much lift. Only thing I don’t like is that when it’s tucked under the seat, it takes up space (in case you like to fold your ankles under the seat - it will be in the way). Seat is wide and comfortable short term. I needed to get a cushion as I sit on it for 12 hours a day and was getting sciatica after a while. Rolls really smoothly. A lot of chairs don’t move as smooth because of their bulkiness, but this one is really smoothly. Very sturdy and well made for the price. Highly recommend.
