Router Bit Sharpening
Q: Can my carbide-tipped router bits and saw blades be sharpened? Where and how?
A: Most carbide-tipped router bits and saw blades can be sharpened to extend their life. Since carbide is being removed, this will slightly change the router bit profile, but the effect will be negligible if done properly. Light touch-ups of simple router bit profiles can be performed with a diamond hone. For more complex profiles and more serious sharpening, locate a qualified carbide-sharpening service in your local Yellow Pages or online.
The Protective Wax Coating On Router Bits
Q: What is that clear coating / protective coating on my bits and how do I remove it?
A: Most MLCS bits are coated with a protective wax coating to defend against chipping and moisture. This coating should be removed prior to use. The coating can be removed by peeling it away with your fingernail or a razor blade. If using a blade, please be careful, both for your own safety and to avoid damaging the carbide.
Router & Forstner Bit Speed (RPM)
Q: What is the recommended RPM (revolutions per minute) for MLCS and K-Premium Router Bits?
| ROUTER BITS | |||||
|---|---|---|---|---|---|
| Large Diameter Sizes | Maximum Recommended RPM | ||||
| 1/4" to 2" | 18,000 | ||||
| 2-1/8" to 2-1/2" | 16,000 | ||||
| 2-5/8" to 3-1/2" | 12,000 | ||||
| Please note that for router bits with a carbide height greater than 1-1/2", the bits should be run at 16,000 RPM or less, and the cut should be made in several passes. To reduce Router speed, use a variable speed router or a Speed Control device. | |||||
| FORSTNER BITS | |||||
|---|---|---|---|---|---|
| Maximum Recommended RPM | |||||
| Sizes | Soft Woods | Hard Woods | |||
| 1/4" to 3/8" | 2400 | 700 | |||
| 1/2" to 5/8" | 2400 | 500 | |||
| 3/4" to 1" | 1500 | 500 | |||
| 1-1/8" to 1-1/4" | 1000 | 250 | |||

Router Bit Maintenance and Storage
Q: Before and after using my router bits, is there anything that I can do to insure a long-lasting bit?
A: Our woodworkers recommend the following to ensure maximum bit life:
- Keep bearings lubricated using our Router Bit Bearing Lube.
- Clean bits off after each use and spray a blade lubricant on them, if it is available.
- Store in a low humidity, room temperature environment.
- Touch up dull bits with Diamond Honing Stones.
- Store bits with silica gel packets to absorb moisture and prevent rust formation.
Router Bit Safety

WARNING
Router Plate Mounting Holes
Q: Does your Router Plate come pre-drilled for my router?
A: No, you must drill appropriate holes to match the configuration of your router. This is true for our All-in- One Router Plate Kits, Aluminum Router Plate Kits, Super Tuff Router Mounts, and the router plates included in our selection of Router Tables.
K-Premium vs. MLCS Router Bits
Q: What is the difference between MLCS and K-Premium Bits?
A: Our K-Premium line of router bits are our premium line of router bits, which we guaranteed to meet or exceed any brand on the market. MLCS bits are excellent bits for the price, a fine match between quality and value. However, the K-Premium bits will stay sharper longer and leave a smoother finish, especially for production work.
