Cleveland C71200 Jobber Drill Bit 1 Mm Hss Oxide 118

Product Description

The CLEVELAND C71200 is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, and similar materials. Manufactured from high speed steel with an oxide finish, this bit measures 1 mm in diameter with an overall length of 1.339 inches and a flute length of 0.472 inches. The 118-degree standard point angle and web-thinned, tapered web geometry improve center-starting accuracy and reduce thrust on entry. Two spiral flutes with a regular helix evacuate chips efficiently during through-hole and blind-hole drilling operations. It is sold individually and meets ASME B94.11M and DIN 338 standards.

This drill bit is suited for light-duty precision work where small-diameter holes are required. The 1 mm diameter and straight cylindrical shank make it appropriate for use in standard drill chucks, CNC drilling centers, drill presses, and hand-held power drills. Typical applications include sheet metal work, electronics enclosures, and fine metalworking tasks performed by machinists, maintenance technicians, and tool-and-die professionals. The general-purpose grade covers a wide range of common workpiece materials encountered in production and repair environments.

Key Features

• 1 mm diameter with 118-degree standard point angle for accurate entry on flat and curved surfaces
• High speed steel construction with oxide coating for improved surface hardness and chip resistance
• Web-thinned, tapered web design reduces drilling thrust and improves point penetration
• Two regular-helix spiral flutes promote consistent chip evacuation
• Straight cylindrical shank fits standard drill chucks without modification
• Meets ASME B94.11M and DIN 338 standards for dimensional accuracy and performance

Compatibility

Designed as a general-purpose OEM-style jobber drill bit suitable for use in standard drill chucks, drill presses, and CNC drilling equipment accepting straight cylindrical shanks in the 0.0000 to 0.0500 inch diameter range.

Installation Notes

Installation and use of small-diameter drill bits should be performed by qualified machinists or maintenance technicians familiar with proper speed and feed selection for the workpiece material. Secure the shank fully in the chuck before operation and confirm the drill press or power tool is in a stable, powered-off state before changing bits. Avoid side-loading bits of this diameter, as small-diameter HSS bits are susceptible to breakage under lateral force. Follow applicable shop safety practices and machine guarding requirements during use.
