Osg 61526 Screw Machine Drill Bit 0.1024 in Hss

Product Description

The OSG 61526 is a screw machine length drill bit designed for high-performance drilling in metalworking and machining applications. Built from high speed steel (HSS) with a coated finish, it measures 0.1024 inches (2.60 mm) in diameter and features a 130-degree faceted point angle for improved centering and reduced thrust. The web-thinned, tapered web design minimizes cutting resistance at the point. With a two-flute spiral configuration and straight-cylindrical shank, this bit is suited for use in drill presses, CNC machining centers, and manual machine tools by machinists and tool-and-die professionals.

This bit is intended for short-hole drilling operations where a compact overall length is required. The screw machine length format provides greater rigidity compared to jobber-length bits, making it well suited for tight-tolerance work in steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. The 5xD flute-to-diameter ratio supports chip evacuation in these materials. It is sold individually and is part of OSG Series 1100.

Key Features

• 0.1024 inch (2.60 mm) cutting diameter with a tolerance of +0 to -0.014 mm
• 130-degree faceted drill point for accurate self-centering and reduced walking
• Web-thinned, tapered web reduces point thrust and improves penetration
• High speed steel construction with coated finish for extended tool life
• Two-flute spiral design promotes efficient chip evacuation
• Screw machine length for added rigidity in precision drilling applications

Compatibility

Designed for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Compatible with standard straight-cylindrical shank tool holders and chucks accepting a 3.00 mm (approximately 0.118 inch) shank diameter.

Installation Notes

Installation and use should be performed by qualified machinists familiar with rotating cutting tool safety. Secure the shank fully in the chuck or collet and verify runout before drilling. Always operate within the spindle speed and feed rate range recommended for the workpiece material and bit diameter. Eye protection and appropriate workholding are required when operating any rotary cutting tool.
