Cleveland C15064 Cobalt Screw Machine Drill Bit 9/32 in

Product Description

The CLEVELAND C15064 is a cobalt screw machine length drill bit built for drilling into tough materials including alloy steels and aluminum. Sized at 9/32 inch (0.2812 inch decimal), it features a 135-degree split point that reduces walking on entry and requires no center punch on most surfaces. The parabolic flute design improves chip evacuation, which matters when drilling through gummy or stringy alloys. The web-thinned construction lowers thrust requirements. Overall length is 2-11/16 inches, making this a short, rigid geometry ideal for confined-space drilling or CNC and drill press work where rigidity is critical. Licensed trades and machinists turn to this bit when standard HSS tooling fails to hold an edge.

The C15064 is suited for production and maintenance drilling in residential and light industrial settings. It performs in right-hand rotation only and is intended for use with standard drill presses, CNC machining centers, or hand-held power drills equipped with a matching collet or chuck. Primary target materials are alloy steels and aluminum, making it a common selection for HVAC fabricators, pipefitters, and maintenance machinists cutting through structural and sheet metal components.

Key Features

• Cobalt construction with M42 material grade for heat and wear resistance in hard alloys
• 135-degree split point reduces walking and cutting force on entry
• Parabolic flute geometry accelerates chip removal in deep or interrupted cuts
• Web-thinned, parallel web configuration lowers thrust and improves hole quality
• Straight-cylindrical shank fits standard drill chucks and collets without adapters
• Meets ASME B94.11M and ANSI specification for dimensional consistency

Compatibility

Designed as a screw machine length replacement bit for right-hand-rotation drilling applications in alloy and aluminum workpieces. Fits any chuck or collet accepting a 0.2813-inch straight-cylindrical shank.

Installation Notes

A licensed machinist or qualified tradesperson should install and operate this tooling in accordance with applicable shop safety standards and machine manufacturer guidelines. Power down and de-energize all equipment before inserting or removing the bit from the chuck. Secure the shank fully within the chuck jaws to the rated gripping depth before operation. Do not exceed the spindle speed recommended for the workpiece material and bit diameter.
