Osg HP245-1063 Solid Carbide Jobber Drill 2.70 Mm

Product Description

The OSG HP245-1063 is a solid carbide jobber-length drill bit designed for high-performance drilling in ferrous materials. It measures 2.70 mm in diameter with an overall length of 56.00 mm and a flute length of 23.00 mm, placing it in the HP245 series engineered for precision and tool life in demanding shop environments. The 140-degree point angle with R-thinned web geometry reduces thrust and promotes self-centering on entry. A WD1 coating adds wear resistance for extended tool life in steel and cast iron applications. Right-hand spiral flutes evacuate chips efficiently in both blind and through-hole drilling operations. This bit is installed and used by machinists and precision fabricators working with CNC machines, drill presses, and hand-held power tools in production and maintenance environments.

This drill is suited for blind hole, cross-hole, and standard drilling operations in steel, alloy steel, and cast iron workpieces. The 5xD flute-to-diameter ratio and regular spiral type make it a reliable choice for general-purpose and high-production drilling at this diameter range. The straight-cylindrical shank with a 3.00 mm shank diameter seats securely in standard collet chucks and drill chucks without modification. It is appropriate for both job-shop and production floor use where consistent hole quality and dimensional accuracy are required.

Key Features

• Solid carbide construction for hardness and wear resistance in ferrous materials
• 140-degree point angle with R-thinned web for reduced thrust and self-centering entry
• WD1 coating for extended tool life in steel and cast iron
• Right-hand spiral flutes with regular helix for efficient chip evacuation
• Straight-cylindrical shank at 3.00 mm for compatibility with standard collet and drill chucks
• Suited for blind hole, cross-hole, self-centering, and standard drilling applications

Compatibility

Designed for use in steel, alloy steel, and cast iron workpieces. Primary workpiece material codes P and K. Compatible with standard collet chucks and drill chucks accepting a 3.00 mm straight-cylindrical shank. Diameter tolerance of +0.002 to +0.012 mm.

Installation Notes

This drill bit is installed by machinists and tool-and-die professionals in CNC machining centers, drill presses, and hand-held rotary tools. Secure the straight-cylindrical shank fully in the chuck before operation and verify runout is within acceptable limits. Coolant-through is not supported on this tool; apply cutting fluid externally when required by the workpiece material. Inspect the cutting edge and web condition before each use and replace the bit at first sign of edge wear or chipping to maintain hole-diameter tolerance.
