Osg HP245-4063 Carbide Jobber Drill Bit 13/32 in

Product Description

The OSG HP245-4063 is a solid carbide jobber-length drill bit designed for high-performance drilling in ferrous metals. It features a 13/32-inch (0.4062 inch decimal) diameter, a 140-degree point angle with R-thinned web geometry, and a WD1 coating that extends tool life in demanding cutting environments. With a regular spiral flute pattern and straight-cylindrical shank, this bit delivers consistent chip evacuation and stable tool holding. It is intended for use by machinists, tool-and-die technicians, and metalworking professionals who require tight-tolerance hole quality in production or job-shop settings.

The HP245-4063 is engineered for drilling in steel, alloy steel, and cast iron. Its 5xD flute-to-diameter ratio supports deeper hole applications where chip clearance is critical. Typical applications include blind hole drilling, cross hole operations, and self-centering entry cuts. The R-thinned point reduces thrust force at entry, making it well suited for both manual setup and CNC machining centers where consistent hole positioning is required.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous metal drilling
• WD1 coating provides enhanced lubricity and heat resistance at the cutting edge
• 140-degree point angle with R-thinned web reduces entry thrust and improves self-centering
• Regular spiral flute with tapered web configuration supports efficient chip evacuation
• Straight-cylindrical shank with 12 mm shank diameter fits standard drill chucks and collets
• Suited for blind hole, cross hole, and self-centering drilling operations

Compatibility

Designed for use in steel, alloy steel, and cast iron workpieces. Compatible with standard straight-shank drill chucks and ER-style collet systems accepting a 12 mm shank diameter. Suitable for CNC machining centers and manual drilling setups within the HP245 series application range.

Installation Notes

Installation and operation should be performed by qualified machinists or tooling technicians familiar with carbide tooling requirements. Secure the shank fully in the chuck or collet before use and verify runout with a dial indicator when hole tolerance is critical. Carbide tooling is brittle and should never be dropped or subjected to impact loading. Always set spindle speed and feed rate according to the workpiece material and machine capability before engaging the cut.
