Osg 8597248 Jobber Drill Bit Wire 40 Tin Vanadium Hss

Product Description

The OSG 8597248 is a jobber-length drill bit designed for high-performance drilling in steel, stainless steel, aluminum, and aluminum alloys. Built from vanadium high-speed steel with a titanium nitride (TiN) coating, this bit delivers extended tool life and reduced friction during cutting. It features a 130-degree drill point angle with S-thinned web geometry for improved self-centering and reduced thrust force at entry. The straight-cylindrical shank measures 3.00 millimeters in diameter, and the overall length is 62.00 millimeters. It belongs to the OSG Series 1600, targeting high-performance production and maintenance drilling applications. Installation is performed by machinists, maintenance technicians, and trade professionals using standard drill chucks or collet holders.

This bit is suited for blind hole drilling, cross-hole drilling, and general through-hole applications across ferrous and non-ferrous workpiece materials. The 2.48-millimeter (0.0976-inch, Wire Size 40) diameter falls within the 0.0500 to 0.1000 decimal inch drill size range, making it a common choice for tapping prep, pilot holes, and precision small-diameter work in steel and stainless steel fabrication, HVAC component manufacturing, and aluminum structural work. The spiral flute with regular helix promotes chip evacuation in both shallow and moderate-depth holes.

Key Features

• Vanadium high-speed steel construction for elevated hardness and wear resistance in steel and stainless steel
• Titanium nitride (TiN) coating reduces surface friction and extends cutting life
• 130-degree drill point angle with S-thinned web improves self-centering and reduces walking on entry
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Two spiral flutes with regular helix promote consistent chip evacuation
• Suitable for blind holes, cross holes, and self-centering drilling applications

Compatibility

Designed for use in steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Compatible with standard drill chucks and collet-style tool holders accepting a 3.00-millimeter straight shank. Suitable for use with manual drill presses, CNC machining centers, and hand-held power drills where the chuck capacity accommodates the shank diameter.

Installation Notes

Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable tolerance for the application. This bit does not support coolant-through delivery; use external cutting fluid or coolant when drilling stainless steel or deep holes in ferrous materials to control heat buildup. Operate at speeds appropriate for the workpiece material and bit diameter — consult the OSG Series 1600 feeds-and-speeds reference for recommended RPM ranges. Inspect the cutting edges and TiN coating for wear or chipping before reuse; a damaged web or worn tip will increase thrust force and reduce hole quality.
