Osg 8608233 Screw Machine Drill Bit 0.0917 in Xpm

Product Description

The OSG 8608233 is a screw machine length drill bit ground from XPM high-speed steel and finished with an XPM coating for extended tool life in demanding production environments. It measures 0.0917 inches (2.33 mm) in diameter with an overall length of approximately 1.77 inches (45.00 mm) and a flute length of approximately 0.51 inches (13.00 mm). The 130-degree split point with X-thinned web reduces thrust force and improves self-centering on entry. With a straight-cylindrical shank at 0.118 inches (3.00 mm) diameter, this bit seats securely in standard drill chucks and quick-change holders. It is a right-hand cut, two-flute design intended for machinists, toolroom technicians, and production drilling operations.

The OSG 8608233 is suited for drilling steel, alloy steel, cast iron, and nickel alloys in screw machine, CNC, and manual drill press applications. Its compact screw machine length — shorter than jobber length — provides added rigidity and reduces deflection in close-tolerance work. The 3xD flute-to-diameter ratio and regular spiral geometry promote efficient chip evacuation in short-hole drilling cycles. This bit is a single-piece, individual-quantity item appropriate for toolcrib stocking or direct-to-machine replacement.

Key Features

• XPM high-speed steel with XPM coating for high-performance cutting and wear resistance
• 130-degree drill point angle with X-thinned web for reduced entry thrust and improved centering
• Screw machine (stub) length for increased rigidity over standard jobber length bits
• Right-hand cut, two-flute spiral design with tapered web configuration
• Straight-cylindrical shank fits standard chucks and collet holders without adapters
• No coolant-through — suited for dry or externally lubricated applications

Compatibility

Designed for drilling steel, alloy steel, cast iron, and nickel alloy workpieces. Fits standard drill chucks and quick-change tooling systems accepting a 0.118-inch (3.00 mm) straight-cylindrical shank. Part of OSG Series 1900.

Installation Notes

Installation and use should be performed by a qualified machinist or toolroom technician familiar with cutting tool selection and machine operation. Before changing tooling, ensure the spindle is fully stopped and the machine is de-energized or locked out per applicable safety procedures. Verify chuck or collet runout is within tolerance before drilling to preserve bit geometry and hole accuracy. Do not use this bit in hammer-drill or impact mode — it is intended for rotary drilling only.
