Precision Twist Drill 5998381 Jobber Drill Bit Wire 35

Product Description

The PRECISION TWIST DRILL 5998381 is a jobber length drill bit in wire gauge size 35, with a decimal diameter of 0.1100 inches. Built from high speed steel (HSS) with a steam oxide coating, this bit delivers reliable performance in general-purpose drilling applications. It features a 118-degree standard point angle, a right-hand spiral flute, and a web-thinned tapered web for improved chip evacuation and reduced thrust. Overall length is 2.625 inches (2-5/8 inches), with a flute length of 1.5 inches. This is a straight-cylindrical shank bit from the Series R18 line, sold individually.

This drill bit is suited for drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It is appropriate for use in general-purpose production and maintenance environments where a wire gauge size 35 hole is required. The 14xD flute-to-diameter ratio provides a stable flute geometry across the full 1.5-inch maximum drilling depth. No coolant-through capability is present, so external cooling or cutting fluid should be applied for harder workpiece materials or extended run times.

Key Features

• Wire size 35 with 0.1100-inch decimal diameter and matching straight-cylindrical shank diameter
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• Steam oxide coating improves lubricity and provides mild corrosion resistance during storage and use
• Right-hand cut, regular spiral, 2-flute design for efficient chip removal
• 1.5-inch maximum drilling depth with a 2.625-inch overall length
• Conforms to ANSI standards; Series R10-R15-R18

Compatibility

Designed as a general-purpose OEM-style jobber length drill bit compatible with standard drill chucks and CNC or manual drilling equipment that accept a 0.1100-inch straight-cylindrical shank. Suitable for workpiece material codes P, M, K, N, and S per standard material classification.

Installation Notes

This bit is installed by machinists, maintenance technicians, and metalworking tradespeople using standard drill chucks rated for the shank diameter. Ensure the chuck is fully seated and tightened before operation. Apply cutting fluid or external coolant when drilling stainless steel, cast iron, or titanium to manage heat buildup and extend tool life. Inspect the point for wear or chipping before each use; a damaged point will affect hole diameter accuracy and surface finish.
