Cleveland C15127 Screw Machine Drill Bit 37 Cobalt

Product Description

The CLEVELAND C15127 is a screw machine length drill bit designed for high-performance drilling in demanding trade and industrial applications. Built from M42 cobalt material with a coated finish, this bit handles harder workpiece materials where standard high-speed steel falls short. The 135-degree split point with web thinning reduces thrust force and improves centering on entry, making it a reliable choice for production drilling. The parabolic flute geometry promotes efficient chip evacuation. At 1-13/16 inches overall length, the screw machine format provides rigidity and minimizes deflection in short-reach drilling operations.

This drill bit is suited for use in CNC machining centers, drill presses, and hand-held power tools where a screw machine length bit is specified. Primary workpiece materials include alloy steel and aluminum, making it a practical tool for metal fabrication shops, maintenance technicians, and precision machining environments. The straight-cylindrical shank seats securely in standard three-jaw chucks and quick-change chuck systems. The Series 2175A designation identifies it within the CLEVELAND cobalt drill line for reorder and toolcrib management purposes.

Compatibility

Designed as an OEM-style replacement or direct tooling selection for applications requiring a wire gauge size 37 screw machine length drill bit with a straight-cylindrical shank in the 0.1000 to 0.1500 inch diameter range.

Installation Notes

Installation and use of this drill bit should be performed by machinists or qualified tradespeople familiar with proper chuck seating and spindle speed selection for the workpiece material. Ensure the drill press or machine spindle is fully stopped before inserting or removing the bit. Inspect the cutting edges and shank for damage before each use. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed rates.
