This carbide straight router bit features a cutting diameter of 1/4" and a cutting length of 1-1/2" with an overall length of 3-5/16". The shank is 1/4" in diameter.

Instructions: Slowly dial up the RPMs on your router to the recommended maximum. Then, dial back if needed to find the “sweet spot”. The sweet spot is the speed at which the least resonant vibration is present. If the sweet spot cannot be achieved within 5,000 RPMs of the max, check the collet for residue or other debris and start over.

• Type: ER Collet• Collet Series: ER32• Size (Inch): 3/4"Our ER collet system is made of special elastic steel material under excellent heat treatment and precise grinding process, so it has precise accuracy, powerful clamping ability, and is durable. This collet can clamp for a specific standard size and its next size. It can be widely used for boring, milling, drilling and tapping as well as for grinding operation, and is available for all sizes.

Solid carbide tipped insert router bits are very durable, versatile and long lasting. The solid carbide insert can be manufactured with very small diameters while still maintaining structural strength. Best for use in detailed applications, inlays and fine grooving. The solid carbide tip is welded into a hardened steel shank.
