Cle-line C23550 No. 10 Screw Machine Drill Bit Hss

Product Description

The CLE-LINE C23550 is a screw machine length (stub length) twist drill bit designed for high-production drilling in metal and other hard materials. Manufactured from heavy-duty high-speed steel with an oxide coating for added lubricity and corrosion resistance, this bit carries a 135-degree split point that reduces walking and requires no center punch on most surfaces. The straight-cylindrical shank measures 0.1933 inches in diameter, and the overall length is 2.25 inches, making it well suited for close-quarter and machine-mounted applications. The web-thinned, tapered web configuration reduces thrust and improves chip evacuation. It is installed by machinists, toolroom technicians, and maintenance trades using drill presses, CNC machines, and handheld power tools.

This bit is sized to No. 10 wire gauge, equivalent to 0.1935 inches decimal, and falls within the 0.1500 to 0.2000 inch diameter range of the CLE-LINE Series 1896 line. Its stub-length body and rigid geometry make it a standard choice for production environments where drill press or turret setups demand shorter-reach tooling. The right-hand spiral fluting and split point geometry suit ferrous metals, plastics, and composite materials encountered in general manufacturing and maintenance repair operations.

Key Features

• 135-degree split point reduces bit walking and lowers required entry force
• Web-thinned tapered web improves chip flow and reduces heat buildup at the tip
• Heavy-duty high-speed steel construction for extended tool life in metal drilling
• Oxide coating adds lubricity and light corrosion resistance
• Screw machine (stub) length provides added rigidity in drill press and CNC setups
• Straight-cylindrical shank fits standard drill chucks without adapter hardware

Compatibility

Designed as a standard screw machine length drill bit for use in drill presses, CNC machining centers, turret lathes, and handheld power tools equipped with chucks sized to accept a 0.1933-inch straight-cylindrical shank. Part of CLE-LINE Series 1896.

Installation Notes

This bit is installed by machinists and maintenance technicians working with metal-cutting equipment. Secure the shank fully in the chuck and verify concentricity before operation. Use appropriate cutting fluid for ferrous metals to extend tool life and manage heat. Inspect the cutting edges before each use and replace bits that show chipping or excessive wear to avoid workpiece damage or tool breakage.
