Osg 653045612 Taper Length Drill Bit 0.4567 in Carbide

Product Description

The OSG 653045612 is a solid carbide taper length drill bit designed for precision drilling in demanding industrial and metalworking applications. With a 0.4567-inch (11.60 mm) diameter and a 140-degree split point, this bit delivers clean entry and reduced thrust in hard or abrasive materials. The X-thinned web reduces cutting resistance at the tip. Coolant-through capability supports high-speed, deep-hole drilling by flushing chips and managing heat at the cutting zone. This bit is suited for machinists, tool-and-die shops, and production environments where hole quality and tool life are critical.

The OSG 653045612 fits production drilling setups requiring a straight shank in standard collets or drill chucks. The 10xD flute-to-diameter ratio and 155.00 mm (6.10-inch) flute length support deep-hole drilling in steel, alloy, and similar materials. It is typically used in CNC machining centers, drill presses, and manual mills where coolant-through capability can be utilized. The bright, uncoated finish is appropriate for use with cutting fluids on ferrous and non-ferrous metals.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• 140-degree point angle reduces thrust and improves self-centering on entry
• X-thinned web lowers cutting resistance and extends tool life
• Coolant-through design supports chip evacuation in deep-hole applications
• 10xD flute-to-diameter ratio enables deep drilling in a single pass
• Right-hand cut with spiral flutes for standard CNC and manual machine compatibility

Compatibility

Designed as an OEM-style replacement or production drill bit in OSG Series 6530. Compatible with standard straight-shank toolholders, collets, and drill chucks accepting a 12.00 mm (0.472-inch) shank diameter.

Installation Notes

Installation is performed by machinists or tooling technicians in machine shop environments. Secure the straight shank fully in the collet or chuck and verify runout before initiating a cut. When using coolant-through capability, confirm that the machine spindle and toolholder support through-coolant flow before use. Follow applicable shop safety procedures and machine manufacturer guidelines for speed and feed selection.
