Osg 61524 Screw Machine Drill Bit 0.0945 in Hss

Product Description

The OSG 61524 is a screw machine length drill bit engineered for high-performance drilling in metalworking and machining applications. It has a 0.0945-inch (2.40 mm) diameter and a 130-degree faceted point angle that provides aggressive penetration and self-centering entry. The bit is made from high speed steel with a coated finish for improved wear resistance and heat management. With a straight-cylindrical shank and web-thinned, tapered web construction, it is designed for use in drill presses, CNC machines, and screw machine setups. Machinists and machine tool operators are the primary installers and users of this bit.

This drill bit is suited for production and job shop environments where short-length, rigid tooling is needed. The screw machine length design provides a compact overall length of 46.00 mm (approximately 1.81 inches), reducing deflection and improving accuracy in close-tolerance holes. Primary workpiece materials include steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. The 5xD flute-to-diameter ratio supports chip evacuation in moderate-depth holes.

Key Features

• 0.0945-inch (2.40 mm) diameter with a diameter tolerance of +0 to -0.014 mm
• 130-degree faceted drill point for self-centering entry and reduced thrust
• High speed steel construction with coated finish for extended tool life
• Web-thinned, tapered web reduces cutting force on entry
• Screw machine length for rigidity and minimal deflection in tight setups
• Right-hand spiral flute with 2 flutes for consistent chip removal

Compatibility

Designed for use in steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Part of the OSG Series 1100 high-performance drill line.

Installation Notes

This bit is installed in standard drill chucks or collet toolholders accepting a 3.00 mm straight-cylindrical shank. Secure the shank fully in the chuck before operating and verify runout is within acceptable limits for the application. Use appropriate cutting fluid or coolant when drilling stainless steel or harder alloys to manage heat buildup. Replace the bit if point chipping or excessive wear is observed, as a damaged drill point increases the risk of workpiece damage and breakage.
