Cleveland C17038 Reduced Shank Drill Bit 5/8 Inch Hss

Product Description

The CLEVELAND C17038 is a reduced shank twist drill bit designed for drilling into steel and cast iron in general-purpose industrial and trade applications. Built from high-speed steel (HSS), it features a 5/8-inch cutting diameter with a 1/2-inch Weldon flat shank that seats securely in compatible drill chucks and end-mill holders. The 118-degree split point promotes accurate starts and reduces walking without a center punch. At 6 inches overall length with a 3-1/8-inch flute length, it handles moderate-depth holes in both light fabrication and production environments. The coated finish extends service life under normal cutting conditions.

The C17038 is suited for metalworking tasks in manufacturing, fabrication shops, mechanical contracting, and maintenance trades. Its reduced shank design allows a 5/8-inch cutting diameter to run in a 1/2-inch chuck or collet, making it practical on standard drill presses and milling machines without requiring a larger spindle. Primary workpiece materials include carbon steel and cast iron. The Weldon flat shank with three flats resists rotation under torque, improving reliability during high-feed drilling operations.

Installation Notes

Install and removal should be performed by a qualified machinist or trades professional with the spindle fully powered down and locked out. Seat the Weldon shank fully into the holder and tighten all set screws against the flats before operation. Inspect the cutting edges and shank for damage before each use. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed selection based on workpiece material.
