Osg 8595084 Screw Machine Drill Bit 0.033 in Wire 66

Product Description

The OSG 8595084 is a screw machine length drill bit designed for high-performance drilling in metal and non-ferrous materials. Built from high speed steel with a coated finish, this bit measures 0.033 inches (Wire Gauge 66) in diameter and features a 150-degree faceted drill point with a web-thinned, tapered web configuration for reduced entry force. The straight-cylindrical shank seats securely in standard chucks and collets. With a 5xD flute-to-diameter ratio and regular spiral fluting, this bit is suited for short-hole drilling where rigidity and chip evacuation are both critical. Licensed machinists, tool-and-die technicians, and precision metalworkers are the primary installers.

This bit is appropriate for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate in production and job-shop environments. Its screw machine length profile — shorter than a jobber-length bit — provides added stiffness when working in drill presses, CNC machining centers, and turret lathes where stub-length tooling is preferred. The 150-degree point angle distributes cutting load across a wider angle, which helps reduce walking on hard or work-hardened surfaces. Two spiral flutes channel chips away from the cutting edge throughout the bore.

Key Features

• Wire Gauge 66 (0.033 inches) diameter with a tight tolerance of plus 0 to minus 0.014 mm
• 150-degree faceted drill point minimizes walking and suits harder workpiece materials
• Web-thinned tapered web reduces thrust force at entry
• High speed steel construction with coated finish for extended tool life
• Screw machine (stub) length provides extra rigidity compared to jobber-length alternatives
• Right-hand cut with regular spiral fluting for efficient chip evacuation

Compatibility

Designed as an OEM-style screw machine length drill bit in the OSG Series 1100 product line, suitable for use in standard drill chucks and collets accepting a 3.00 mm straight-cylindrical shank across drill presses, CNC lathes, and machining centers.

Installation Notes

This bit is installed by machinists or tool-and-die technicians in machine tool spindles — always ensure the machine is fully powered down and locked out before changing tooling. Confirm chuck or collet size is compatible with the 3.00 mm shank before tightening. Use recommended cutting fluids or coolant appropriate to the workpiece material to preserve coating integrity and tool life. Do not exceed the spindle speed range specified for the workpiece material and bit diameter.
