Osg 8595081 Screw Machine Drill Bit 0.032 Inch Hss

Product Description

The OSG 8595081 is a screw machine length drill bit designed for short-hole drilling applications where rigidity and precision matter. Built from high speed steel (HSS) with a coated finish, this bit features a 150-degree faceted drill point and a web-thinned, tapered web configuration for reduced thrust and cleaner entry. The straight-cylindrical shank measures 3.00 millimeters in diameter and fits standard drill chucks used in machining centers, drill presses, and CNC equipment. At 38.00 millimeters overall length, the stub-length profile minimizes deflection in tight work envelopes. This bit is used by machinists and tool-and-die professionals requiring consistent performance on small-diameter holes.

The OSG 8595081 is suited for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpiece materials. Its screw machine length format makes it a go-to choice for production environments, instrument manufacturing, and precision fabrication work where a standard jobber-length bit would introduce excess flex. The 2-flute regular spiral geometry provides efficient chip evacuation in these materials. Wire gauge size 67 corresponds to a decimal diameter of 0.032 inches (0.81 mm), placing it squarely in the micro-drilling range common in electronics and precision assembly applications.

Key Features

• High speed steel construction with coated finish for extended tool life on steel and aluminum workpieces
• 150-degree faceted drill point reduces walking on entry and improves hole location accuracy
• Web-thinned, tapered web lowers axial thrust, critical at 0.032 inch diameters
• Screw machine (stub) length profile at 38.00 mm overall minimizes deflection
• 2-flute regular spiral geometry supports reliable chip evacuation in ferrous and non-ferrous materials
• Diameter tolerance of +0 to -0.014 mm for consistent hole sizing in production runs

Compatibility

Designed as an OEM-style replacement and production cutting tool for use in standard straight-cylindrical shank drill chucks across drill presses, machining centers, and CNC drilling equipment accepting 3.00 mm shank tooling. Compatible primary workpiece materials include steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tool operators familiar with micro-drilling procedures. Secure the straight-cylindrical shank fully in a properly sized collet or chuck before operation, and verify spindle runout is within acceptable limits to avoid bit breakage at this diameter. Power down and de-energize the machine spindle completely before bit changes. At 0.032 inch diameter, excessive feed pressure or misaligned workpiece fixturing are the primary causes of bit fracture.
