Osg HP245-3583 Solid Carbide Jobber Drill Bit 0.3583 in

Product Description

The OSG HP245-3583 is a jobber-length drill bit designed for precision hole-making in demanding materials. Built from solid carbide, it delivers the rigidity and wear resistance needed for production drilling in hardened steels, cast iron, stainless steel, and similar difficult-to-machine workpieces. The 140-degree split point reduces walking and lowers thrust requirements at entry. The WD1 coating provides added surface hardness and lubricity to extend tool life between regrinds. At 9.10 mm (0.3583 inches) diameter with a 103.00 mm overall length, this bit fits standard drill chucks and CNC machining center spindles running coolant-free applications.

This drill bit is suited for metalworking and machining operations in job shop, production, and maintenance-repair environments. It is used in vertical machining centers, drill presses, and manual or CNC lathes where a 10.00 mm shank and jobber-length reach are required. The 5xD flute-to-diameter ratio provides adequate chip clearance for moderate-depth holes without the need for peck cycles in most ductile metals. Licensed machinists, toolroom technicians, and precision fabrication shops are the primary users of this tooling.

Key Features

• Solid carbide construction for rigidity and extended tool life in hard materials
• 140-degree drill point reduces entry walking and decreases thrust load
• WD1 coating adds surface hardness and reduces built-up edge formation
• R-thinned web improves chip flow and reduces axial cutting force
• 5xD flute-to-diameter ratio balances chip evacuation with core strength
• 10.00 mm shank diameter fits standard ER collets and drill chucks

Compatibility

Designed as an OEM-style replacement or direct tooling selection for machining centers, drill presses, and CNC turning centers accepting a 10.00 mm shank jobber-length drill bit in the 0.3500 to 0.4000 inch (9.00 to 10.00 mm) diameter range.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the shank fully into the collet or chuck before operation and verify runout with a dial indicator where tolerances are critical. Power down and lock out the spindle before changing tooling. Do not exceed the recommended feed and speed parameters for the workpiece material and machine horsepower rating.
