Precision Twist Drill 5995868 Jobber Drill Bit Wire 4

Product Description

The PRECISION TWIST DRILL 5995868 is a high speed steel jobber-length drill bit in wire gauge size 4, with a decimal diameter of 0.2090 inches. Built for general-purpose drilling, it features a 135-degree split-point tip with web thinning for faster penetration and reduced walking on entry. The bronze coating provides added lubricity and surface hardness. With an overall length of 3.75 inches and a 2.5-inch spiral flute, this bit delivers consistent chip evacuation and accurate hole placement. Licensed machinists, maintenance technicians, and metalworking tradespeople are the primary installers.

This jobber drill is designed for drilling into steel, stainless steel, cast iron, superalloys, and titanium. The regular spiral flute geometry and tapered web configuration make it suited for both production drilling and field service work. The straight cylindrical shank fits standard drill chucks without modification. It belongs to the HX10-HX15-HX18 series and conforms to ANSI specifications, making it a straightforward drop-in for shops already standardized on that series. Applications range from structural fabrication and equipment repair to MRO drilling across ferrous and exotic workpiece materials.

Key Features

• High speed steel construction handles steel, stainless steel, cast iron, superalloys, and titanium
• Bronze coating improves lubricity and extends tool life in ferrous materials
• Regular spiral flute with tapered web promotes steady chip removal
• Straight cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as an OEM-style replacement and standard jobber drill for applications within the PRECISION TWIST DRILL HX10-HX15-HX18 series, conforming to ANSI specifications for wire gauge drill bits in the 0.2000 to 0.2500 inch diameter range.

Installation Notes

Install in a keyed or keyless drill chuck rated for straight-shank bits at the appropriate RPM for the workpiece material and bit diameter. Power down or de-energize the machine and secure the workpiece before changing bits. Apply cutting fluid or coolant at the entry point when drilling stainless steel, cast iron, or superalloys to manage heat buildup. Follow shop safety protocols and applicable ANSI machining standards during operation.
