Two flute Metric Straight bit
Carbide TippedIn 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 a12,7 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.

Fortunately, this is pretty easy. The best way to prolong the life of a router bit is to keep it clean. And what you need to do varies with the type of bit.
Note: Sharpening is extremely important too.
To clean bits without bearings, first blow off any dust. Then remove any resin that has built up. (Resin places a drag on the bit which can cause it to overheat and burn.)
Resin removers are available. It's the same stuff you use to clean your saw blades.
To clean bits with bearings, first, remove the bearing. Then clean the bit as you did with non-bearing bits.
It's important to remove the bearings because even though router bearings are "sealed," resin remover can sneak in and dissolve the bearing grease. If this were to happen, you would be faced with the problem of trying to lubricate a sealed bearing.
Despite the claims of bearing grease sellers, we've never had much luck with this. Once that grease is gone, just go buy a new bearing.
Periodically inspect the shanks of your router bits for rust or burrs. Either of these can be removed quickly with ScotchBrite®. Left on, they can interfere with your ability to properly tighten the bit in the collet.
If you've got a router with variable speed, then you've got the power to improve the quality of your cut. In general, the larger the bit, the slower the speed you need. The perfect solution for dealing with varying bit sizes is a variable speed router.
Here are general guidelines for most bits:
| Bit size | Bit size | rpm |
| Small 12.7 mm | 1/16" to 1/2" | 22,000+ |
| 12,7 mm 28,6 mm | 1/2 to 1 1/8" | 14,000 - 18,000 |
| 28.6 mm 50,8 mm | 1 1/8" to 2" | 12,000 - 14,000 |
| Bit size | Bit size | rpm |
| 50,8 mm 63,5 mm | 2" to 2 1/2" | 12,000 - 14,000 |
| 63,5 mm - large | 2 1/2" and up | 8,000 - 12,000 |
