CMT Weatherseal Bit - 1/8 in. Dia. - 1/4 in. Shank

CMT Weatherseal Bit – 1/8 in. Dia. – 1/4 in. Shank

With CMT router bits make your house more energy efficient by insulating old doors and windows. CMT Weatherseal router bits are perfect for grooves in door and window frames to accommodate wind-blocking inserts. Made of solid carbide for strength and endurance. Special economical double-sided design lets you save money by offering two tips in one router bit, with the same features as the one-sided weather seal router bits.

 

 

Safety tips: Dust and chips from laminate materials are hazardous to your health and safety. Always wear a dust mask and eye protection when routing.

Safety precautions: never use damaged or worn bits. Always work at the recommended proper feed rate without forcing the bit. Pay particular attention when making the initial cut with a small diameter bit. For best results when working with small diameter bits, cut more than one pass.

How CMT produces high-quality router bits

• Turning, Milling, and Cutting CMTs biggest investment in recent years has been in upgrading production. Today, all machinery at CMT is fully automated. Specially trained operators run CNC machines to ensure our router bits and boring bits' shanks and bodies are accurate and perfectly balanced.
• Heat forged steel bodies for large diameter bits No router bits are the same, not even in the way they are made. Certain bits require a few more steps than others, like heat forging the steel of larger-sized bits before turning it into precise bit bodies. This extra step produces a radial grain orientation, offering large diameter bits extra strength and durability.
• Brazing We have pioneered the art of brazing. Not only does our unique custom–designed computerized brazing equipment help eliminate the inconsistencies found in old fashioned hand brazing, but our silver–copper–silver brazing ‘sandwich’ provides a tight bond between the steel and the carbide, with a shock absorbing effect to protect the carbide tips when cutting harder woods.
• Specially formulated carbide for specific applications In woodworking, you have to cut every kind of material, so we make sure that our carbide tips can handle each job. This means specially formulating the carbide of each tool so that the compositions vary from being super hard (for tough cutting jobs like laminates) to being less hard (to absorb the impact when cutting large profiles) and everything in between.
• Grinding and Sharpening The final step in the production process is no different from the rest: sharpening and grinding are done to extreme precision on multi–axis CNC machines. Each bevel and angle is ground or sharpened to the micron to produce a cutting edge that is both razor sharp yet extremely durable.
