Hertel 66693227 Wire 36 Hss Tialn Jobber Drill Bit

Product Description

The HERTEL 66693227 is a high speed steel (HSS) jobber-length drill bit in wire gauge size 36, with a decimal diameter of 0.1065 inches. It features a 135-degree split point with web thinning for faster penetration and reduced walking on hard materials. The TiAlN coating improves heat resistance and extends tool life in demanding drilling applications. At 2.5 inches overall length with a 1.4375-inch flute length, this is a compact, precision drill suited for production and maintenance work. Licensed machinists, millwrights, pipefitters, and mechanical contractors commonly use bits in this size range for small-diameter holemaking in metal components.

This drill bit is intended for holemaking in stainless steel, cast iron, and other ferrous materials where a tough, heat-resistant coating is required. The straight cylindrical shank fits standard drill chucks without modification. The regular spiral flute geometry provides consistent chip evacuation in both manual and machine drilling setups. It is well suited for CNC drilling, drill press work, and hand-held power tool use in fabrication, field service, and maintenance environments.

Key Features

• Wire gauge size 36 - 0.1065 inches decimal diameter for precise small-hole drilling
• 135-degree split point with web thinning reduces thrust and minimizes drill walking
• TiAlN coating provides high heat resistance and improved tool life in ferrous materials
• High speed steel (HSS) construction rated for heavy-duty service
• Regular spiral flute geometry promotes efficient chip evacuation
• Straight cylindrical shank with 0.0938-inch shank diameter for standard chuck compatibility

Compatibility

Designed as a jobber-length HSS drill bit for use in standard drill chucks accepting straight cylindrical shanks. Primary workpiece materials listed are stainless steel and cast iron. Meets NAS specification designation for tooling.

Installation Notes

This drill bit is installed and used by machinists, pipefitters, and mechanical tradespeople performing holemaking operations. Secure the straight shank firmly in a drill chuck before use and verify the chuck key is removed before starting the machine. Coolant-through is not supported on this bit, so apply cutting fluid externally when drilling stainless steel or cast iron to manage heat buildup. Do not exceed the recommended maximum drilling depth of 1.0 inch per pass without retracting to clear chips.
