Chicago-latrobe 45706 Jobber Drill Bit Wire 36 Hss Oxide

Product Description

The CHICAGO-LATROBE 45706 is a jobber length drill bit designed for high-performance drilling in demanding trade and industrial applications. Built from high speed steel with an oxide coating, it carries a wire gauge size of 36, equal to 0.1065 inches in decimal. The 135-degree split point reduces walking on contact and lowers the thrust needed to penetrate hard materials. At 2.5 inches overall length with a 1.4375-inch flute, this bit is sized for the short, controlled cuts common in fabrication, mechanical, and maintenance work. Licensed and unlicensed machinists, pipefitters, and maintenance mechanics reach for this type when drilling ferrous metals.

The 45706 is suited for drilling cast iron, stainless steel, and carbon steel in both shop and field settings. The right-hand spiral flute evacuates chips cleanly, reducing heat buildup in the cut zone. The straight cylindrical shank seats in standard drill chucks without adapters, making it compatible with most portable and bench-mounted drills. It meets NAS 907 Type B specification, a standard recognized in aerospace and precision metalworking environments. This bit is sold individually and is typically stocked in multiples for production or service truck use.

Key Features

• Wire size 36 (0.1065 inches decimal) with tight diameter tolerance of -0.0005 to 0.0000 inches
• 135-degree split point reduces drill walk and entry thrust on hard materials
• High speed steel construction with oxide finish for wear and heat resistance
• Web-thinned, tapered web configuration improves chip clearance and cutting efficiency
• Regular spiral, 2-flute design for balanced chip evacuation in ferrous metals
• Meets NAS 907 Type B specification for precision and heavy duty grade performance

Compatibility

Designed for drilling cast iron, stainless steel, and carbon steel. The straight cylindrical shank fits standard drill chucks across portable and stationary drilling equipment. Conforms to NAS 907 Type B specification as noted in the product attributes.

Installation Notes

Installation of this drill bit is performed by machinists, maintenance mechanics, pipefitters, and similarly trained trades. Secure the straight shank fully in the chuck and verify chuck key is removed before operation. Use appropriate cutting fluid or coolant when drilling stainless steel or hardened stock to extend bit life and control workpiece temperature. Follow applicable shop safety and OSHA machine guarding requirements when operating drilling equipment.
