Osg 11522215 Screw Machine Drill Bit Wire 36 Hss

Product Description

The OSG 11522215 is a screw machine length drill bit designed for high-performance metal cutting in demanding trade and production environments. Built from high-speed steel with a coated finish, this bit features a 130-degree faceted point and web-thinned construction that reduces entry force and improves chip clearance. At 1.8898 inches overall length with a 0.1065-inch cutting diameter (wire size 36), it is sized for compact, close-tolerance drilling applications. The straight-cylindrical shank measures 0.1181 inches in diameter, fitting standard drill chucks. It carries a 3xD flute-to-diameter ratio with a regular spiral and tapered web configuration for consistent performance in production drilling.

This bit is suited for drilling steel, alloy steel, aluminum, aluminum alloy, and aluminum silicate workpieces. The screw machine length format makes it appropriate for CNC machining centers, drill presses, and turret lathes where stub-length rigidity and reduced deflection are priorities. It is used by machinists, tool-and-die shops, and maintenance technicians working in metalworking and fabrication settings. The right-hand cutting direction and 2-flute spiral design support efficient chip evacuation in both through-hole and blind-hole applications.

Key Features

• Wire size 36 cutting diameter: 0.1065 inches (2.71 mm)
• 130-degree faceted point angle for reduced thrust and clean entry
• Web-thinned, tapered web construction improves chip flow
• High-speed steel construction with coated finish for extended tool life
• Screw machine (stub) length for increased rigidity and reduced deflection
• Right-hand cut, 2-flute regular spiral design

Compatibility

Designed for use in drilling steel, alloy steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Fits standard drill chucks accepting a 0.1181-inch straight-cylindrical shank. Part of OSG Series 1150.

Installation Notes

Install and remove drill bits only with the machine at a full stop and power disconnected. Secure the straight-cylindrical shank firmly in the chuck before operation to prevent runout. Use appropriate cutting fluid or coolant as required by the workpiece material; this bit does not support internal coolant-through delivery. Inspect the cutting edges and point for wear before each use, and replace the bit if chipping or deformation is observed.
