Chicago-latrobe 70132 Hss Jobber Drill Bit No. 32

Product Description

The CHICAGO-LATROBE 70132 is a titanium nitride (TiN) coated, high speed steel jobber length drill bit in wire gauge size No. 32, equivalent to 0.1160 inches in decimal diameter. It features a standard 118-degree split-point geometry with a web-thinned tip that reduces walking and cutting force on entry. The two-flute spiral design with a regular helix evacuates chips efficiently during through-hole operations. Overall length is 2.75 inches with a 1.625-inch flute length and a straight-cylindrical shank measuring 0.1160 inches in diameter. The TiN coating extends tool life versus uncoated HSS by reducing friction and heat buildup at the cutting edge. This bit suits general-purpose drilling in production, maintenance, and fabrication settings.

The 70132 is suited for drilling cast iron and steel in light to medium industrial and trade applications. Its jobber length format makes it compatible with standard drill presses, hand drills, and CNC drill heads. The straight-cylindrical shank seats directly into standard three-jaw chucks without requiring a collet adapter. Typical use cases include sheet metal work, structural steel fabrication, pipe fitting layout, and general mechanical assembly where a wire-gauge No. 32 hole is required. The Series 150T designation places it in a general-purpose line intended for broad material coverage rather than high-production specialty drilling.

Key Features

• Wire gauge No. 32 size, 0.1160 inches decimal diameter, diameter tolerance -0.0005 to 0.0000 inches
• TiN (titanium nitride) coating for reduced friction and extended cutting life versus bare HSS
• 118-degree standard point angle with web-thinned, tapered web for reduced thrust on entry
• Two-flute regular spiral design for consistent chip evacuation in steel and cast iron
• Straight-cylindrical shank fits standard drill chucks without adapters
• Conforms to DIN 338 jobber length standard

Compatibility

Designed as a general-purpose jobber length drill bit for use in standard three-jaw drill chucks on hand drills, drill presses, and CNC drilling equipment. Primary workpiece materials listed by the manufacturer are cast iron and steel.

Installation Notes

A licensed machinist, millwright, or experienced tradesperson should secure the shank fully in the chuck jaws before operation to prevent runout or bit ejection. Ensure the workpiece is clamped or fixtured before drilling to prevent spin. Use appropriate cutting fluid or coolant on steel to manage heat, noting this bit is not coolant-through rated. Inspect the cutting edges for wear or chipping before each use, as a dull TiN-coated bit should be replaced rather than reground by field personnel without proper equipment.
