Cleveland C70314 Screw Machine Drill Bit Wire 10 Hss

Product Description

The CLEVELAND C70314 is a screw machine length drill bit designed for high-speed steel drilling in metalworking and fabrication applications. Built to ASME B94.11M standards and meeting NAS 907 Type C specification, this heavy-duty bit features a 135-degree split point with web thinning for fast penetration and reduced walking on entry. The straight-cylindrical shank measures 0.1935 inches in diameter, matching the wire size 10 (0.1935 inch decimal) cutting diameter. At 2.25 inches overall length, the stub-style screw machine geometry provides added rigidity over jobber-length bits, making it well suited for production drilling in tight clearances.

This drill bit is intended for right-hand cut drilling into alloy steels and aluminum. The screw machine length format is a standard choice for drill press, CNC, and turret lathe operations where a shorter, stiffer tool reduces deflection and improves hole accuracy. The bright uncoated finish suits general-purpose use and allows easy regrinding. With a 1-3/16 inch flute length and 1-1/16 inch shank length, the C70314 fits standard chucks and collet holders used in production shop environments. It is sold individually with a minimum order quantity of 12 units.

Installation Notes

Installation and use of this drill bit should be performed by a qualified machinist or tooling technician. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits. Always follow machine manufacturer guidelines for spindle speed and feed rate based on workpiece material. Inspect the cutting edges before each use and discontinue use if chipping or excessive wear is present.
