Osg 61562 Screw Machine Drill Bit 0.2441 in Hss

Product Description

The OSG 61562 is a screw machine length drill bit designed for high-performance metal drilling applications. It has a 0.2441-inch (6.20 mm) diameter, a 120-degree faceted point angle, and is constructed from high speed steel with a coated finish. The screw machine length format provides a shorter, stiffer body compared to jobber-length bits, reducing deflection and improving hole accuracy. The two-flute spiral design with web thinning promotes efficient chip evacuation. This bit is suited for use in machining centers, drill presses, and hand-held power tools operated by machinists, tool-and-die workers, and maintenance technicians.

The OSG 61562 is intended for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Its screw machine length and high-performance grade make it a practical choice for production drilling environments where rigidity and repeatability matter. The straight cylindrical shank with an 8.00 mm (approximately 0.315 inches) diameter fits standard drill chucks and collet holders. The tapered web configuration and web-thinned geometry reduce thrust force at entry, which is particularly useful when drilling harder alloys and stainless steel grades. It is sold individually and is appropriate for both light shop use and repetitive production runs.

Key Features

• 0.2441-inch diameter with a tight tolerance of +0 to -0.022 mm for precise hole sizing
• 120-degree faceted point angle with web thinning reduces thrust and improves centering
• High speed steel construction with coated finish extends cutting life on ferrous and non-ferrous materials
• Screw machine length body (overall length 75.00 mm, approximately 2.95 inches) provides added rigidity over jobber-length bits
• Two-flute regular spiral design promotes consistent chip removal
• Right-hand cut, straight cylindrical shank fits standard chucks and collet systems

Compatibility

Designed for use in standard drill chucks and collet holders accepting an 8.00 mm straight cylindrical shank. Suitable for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces within the 0.2000-inch to 0.2500-inch drill diameter range.

Installation Notes

Installation and use should be performed by a qualified machinist or trained technician familiar with rotating cutting tools. Secure the shank fully in the chuck or collet and verify runout before beginning a cut. Always power down and de-energize the machine before changing bits. Follow the machine manufacturer and tooling manufacturer guidelines for feed rate and spindle speed when drilling stainless steel or hardened alloys to avoid premature tool wear.
