Cleveland C11671 Jobber Drill Bit No.17 0.173in Hss

Product Description

The CLEVELAND C11671 is a jobber-length twist drill bit in wire gauge size No. 17, equivalent to 0.1730 inches in diameter. Built from high-speed steel (HSS) with a bright uncoated finish, it features a 135-degree split point that reduces walking on entry and lowers thrust force at the start of a cut. The web-thinned, tapered web design improves chip clearance and reduces the force required to push through material. At 3.375 inches overall length with a 2.1875-inch spiral flute, this is a standard jobber format suited for bench drills, handheld drills, and CNC setups running at appropriate speeds. Installation is performed by trade professionals in metalworking and fabrication environments.

The C11671 is rated for primary use in aluminum and is listed under NAS 907 Type B, making it appropriate for aerospace and precision fabrication work. The straight-cylindrical shank at 0.1730 inches diameter fits standard drill chucks without adapters. The regular spiral flute pattern and right-hand cut make it compatible with conventional drilling machines. With a 2-flute configuration and web-thinned geometry, chip evacuation is efficient for non-ferrous materials. This bit is part of Cleveland Series 2222, a heavy-duty line designed for consistent performance in production and maintenance drilling applications.

Installation Notes

This bit is installed by machinists, fabricators, and maintenance technicians using standard drill presses, handheld drills, or CNC spindles. Secure the shank fully in the chuck before operation and confirm the chuck is tightened with a key or by the appropriate method for keyless chucks. Select spindle speed appropriate for the workpiece material and bit diameter according to published feeds-and-speeds references for HSS tooling. Replace the bit if visible wear, chipping, or burning is observed during use.
