1/4" Shank 3/8CD 1CL 2.5" OAL. If you are looking to get the most out of your time and money through more efficient production, but want nothing less than a beautiful clean edge on your finished piece then you definitely must include CMT Straight Bits in your collection. These razor-sharp, double-faced cutters perfectly synthesize the characteristics and advantages that define quality CMT products. Made of special Fatigue Proof® steel and the best carbide, our straight bits can withstand even the heaviest work load and still give you a smooth, precise cut every time. You also get exceptional chip ejection to allow cleaner and more constant cutting. The surface of all CMT bits is protected with our trademark orange Industrial PTFE Coating to help keep the bit from collecting resin, pitch and other residue. CMT Straight Bits allow production at an industrial scale on a variety of plywoods, composites and natural woods. CMT produces 61 straight bits in almost every size you need. Safety tips: Never use damaged or worn down bits. Always work at the proper feed speed without forcing the bit. Pay particular attention when making the initial cut into the wood with a small diameter bit. For best results when working with small diameter bits, run the cut more than one time.
