Cleveland C70261 Screw Machine Drill Bit 7/32 in Hss

Product Description

The CLEVELAND C70261 is a screw machine length drill bit designed for high-speed, close-tolerance drilling in metal fabrication, machining, and maintenance applications. Built from high-speed steel with a bright/uncoated finish, this 7/32 inch (0.2188 inch) diameter bit features a 135-degree split point that reduces walking and lowers thrust requirements at entry. The web-thinned, parallel web construction improves chip evacuation and cutting efficiency. At 2-3/8 inches overall length, it is shorter than jobber-length bits, making it well suited for drill press and CNC work where rigidity and accuracy are critical. The two-flute spiral design handles a range of materials cleanly.

This bit is intended for production and shop floor use where repeat-accuracy drilling in alloy steel, aluminum, and similar workpiece materials is required. The screw machine length profile fits standard drill chucks and collets without modification, making it a practical choice for machinists, millwrights, and maintenance technicians working with bench-top or turret-style machines. It conforms to ASME B94.11M and NAS 907 Type C specifications, confirming dimensional consistency across the series.

Key Features

• 135-degree split point reduces entry walking and lowers required feed pressure
• Web-thinned, parallel web construction for improved chip flow and reduced heat buildup
• High-speed steel construction rated for heavy-duty cutting duty
• Screw machine (stub) length at 2-3/8 inches OAL increases rigidity over jobber-length alternatives
• Right-hand cut, straight-cylindrical shank fits standard drill chucks and collets
• Meets ASME B94.11M and NAS 907 Type C dimensional standards

Compatibility

Designed as a Series 2330 screw machine length drill bit suitable for use in alloy steel and aluminum workpieces. Compatible with any drill press, CNC machine, or hand drill accepting a straight-cylindrical shank of 0.2188 inch diameter. No brand-specific model compatibility was stated in the product data.

Installation Notes

Install in a properly rated drill chuck or collet and verify the shank is fully seated and secure before operation. Ensure the workpiece is clamped or fixtured to prevent rotation during drilling. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain dimensional accuracy. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.
