Cleveland C12191 Taper Shank Drill Bit 35/64 in 2MT Hss

Product Description

The CLEVELAND C12191 is a taper shank drill bit engineered for general-purpose drilling in metal, wood, and similar materials. It features a 35/64 inch (0.5469 inch decimal) diameter, a No. 2 Morse taper shank for secure mounting in compatible drill presses and machine spindles, and a 118-degree standard point angle suited for a wide range of workpiece materials. The spiral flute geometry promotes chip evacuation during drilling. The high-speed steel construction with an oxide finish provides surface protection and is appropriate for production and maintenance machining environments. This bit is web-thinned to reduce thrust requirements at the point. Licensed machinists and maintenance technicians are the primary installers.

The C12191 is designed for use in drill presses, lathes, and milling machines equipped with a No. 2 Morse taper spindle or sleeve. It suits general-purpose hole-making operations in production shops, maintenance facilities, and toolrooms. The 4-7/8 inch flute length accommodates moderate-depth drilling applications, while the 8-3/4 inch overall length fits standard taper-spindle machine setups. Right-hand cutting direction is standard for conventional machine operation.

Key Features

• 35/64 inch diameter with a tight tolerance of +0.0000 to -0.0012 inch for accurate hole sizing
• No. 2 Morse taper shank for positive drive in compatible machine spindles
• 118-degree standard point angle suitable for general-purpose drilling
• Web-thinned point reduces drilling thrust and improves penetration
• High-speed steel construction with oxide finish for surface protection
• Spiral flute, right-hand cut, regular spiral for efficient chip removal
• Meets ASME B94.11M standard

Compatibility

Designed for use in drill presses, lathes, and milling machine spindles accepting a No. 2 Morse taper. A taper sleeve or adapter may be required depending on the machine spindle size.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with taper-shank tooling. Ensure the machine spindle and taper shank are clean and free of chips or burrs before seating the bit to achieve proper contact and runout. Always power down and lock out the machine before changing tooling. Use appropriate cutting fluid for the workpiece material and confirm spindle speed is set per standard feeds-and-speeds practice for the material and diameter.
