Precision Twist Drill 5999300 Wire Size 95 Hss Drill Bit

Product Description

The PRECISION TWIST DRILL 5999300 is a jobber-length drill bit in wire gauge size 95, ground from high speed steel with a bright uncoated finish. It carries a 118-degree standard point angle and a right-hand spiral flute for general-purpose drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. The straight-cylindrical shank measures 0.0067 inches in diameter, matching the drill diameter exactly. Overall length is 0.75 inches with a usable flute length of 0.0625 inches. This bit belongs to the R18P series and conforms to ANSI standards. Machinists, tool-and-die workers, and maintenance technicians reach for this size when drilling fine pilot holes or precision bores in hard and exotic materials.

This drill bit is suited for light-duty bench drilling, drill press work, and precision machining operations where tight hole tolerances in small diameters are required. The 0.0067-inch decimal diameter places it firmly in the micro-drill category, making it appropriate for instrument work, electronics fabrication, and fine metalworking applications across both job-shop and production-floor environments. The regular spiral geometry and tapered web configuration support chip evacuation in shallow-depth drilling passes up to a maximum depth of 0.0625 inches.

Key Features

• Wire gauge size 95 with a decimal diameter of 0.0067 inches for micro-precision drilling
• 118-degree standard point angle with web-thinned, tapered web for reduced thrust in hard materials
• High speed steel construction handles steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium
• Bright uncoated finish for easy visual inspection of cutting edge condition
• Right-hand, regular-spiral, two-flute design for efficient chip removal in shallow holes
• Straight-cylindrical shank for secure seating in standard drill chucks and collets
• Conforms to ANSI specification designation for dimensional consistency

Compatibility

Designed as a general-purpose jobber-length drill bit conforming to ANSI standards; compatible with any standard drill chuck or collet sized to accept a 0.0067-inch straight-cylindrical shank.

Installation Notes

This bit is installed by a machinist or tooling technician into a drill press, CNC machine, or precision hand drill with an appropriate collet or micro-chuck. Secure the shank fully in the chuck and verify runout before drilling. Because of the extremely small diameter, use a peck-drilling cycle and low feed pressure to avoid bit deflection or breakage. Always wear appropriate eye protection and follow shop safety procedures when working with micro-diameter tooling.
