Chicago-latrobe 45687 Jobber Drill Bit Wire 17 Hss 135

Product Description

The CHICAGO-LATROBE 45687 is a jobber-length drill bit engineered for heavy-duty cutting in ferrous and hard materials. Built from high-speed steel with an oxide coating, this bit carries a 135-degree split point that reduces walking on contact and requires less feed force than a standard 118-degree grind. The wire size 17 designation corresponds to a decimal diameter of 0.1730 inches. The two-flute spiral design with a web-thinned, tapered web promotes efficient chip evacuation and helps maintain cutting speed during extended production runs. Licensed HVAC technicians, machinists, and industrial tradespeople commonly reach for this series when drilling through cast iron, stainless steel, and carbon steel.

The 45687 fits standard production and maintenance drilling applications where wire-gauge sizing is specified on engineering drawings or fabrication callouts. The straight-cylindrical shank seats securely in keyed or keyless chucks across a full range of portable and bench-mounted drill equipment. With a 3-3/8-inch overall length and a 2-3/16-inch flute length, it provides adequate reach for typical through-hole work on plate, structural, and sheet stock within the 0.1500 to 0.2000 inch drill bit size range. The bit meets NAS 907 Type B standards and is rated for high-performance, heavy-duty service.

Key Features

• 135-degree split point reduces drill walk and lowers required feed pressure on hard materials
• High-speed steel construction with oxide coating for corrosion resistance and improved surface lubricity
• Web-thinned, tapered web for faster chip clearing and reduced heat buildup
• Right-hand, regular spiral flute geometry optimized for cast iron, stainless steel, and steel
• Straight-cylindrical shank at 0.1730 inches diameter fits standard drill chucks without adapters
• Meets NAS 907 Type B specification for dimensional and performance requirements

Compatibility

Designed as a heavy-duty OEM-style jobber-length drill bit for use on cast iron, stainless steel, and steel workpieces where a wire size 17 (0.1730 inch) diameter is required. Fits any standard keyed or keyless chuck that accepts a straight-cylindrical shank at this diameter.

Installation Notes

A licensed machinist or qualified tradesperson should select appropriate cutting speed and feed rate for the workpiece material before use. Secure the workpiece fully before drilling and confirm the chuck is tightened properly on the straight shank. Apply cutting fluid or coolant when drilling stainless steel or other work-hardening alloys to extend bit life. Inspect the cutting edges and split point before each use and replace the bit if chipping or dulling is observed.
