Osg 653042312 Taper Length Drill 27/64 in Solid Carbide

Product Description

The OSG 653042312 is a solid carbide taper length drill bit designed for precision drilling in demanding production and machining environments. Built to Series 6530 specifications, it features a 140-degree split point with X-thinned web geometry that reduces thrust force and improves centering accuracy. The EgiAs coating provides enhanced wear resistance and heat dissipation during high-speed cutting operations. With a flute-to-diameter ratio of 10xD and through-coolant capability, this drill is suited for deep-hole applications where chip evacuation and thermal management are critical. Installed by machinists and tooling technicians in CNC machining centers and drill presses.

This taper length drill is used in metalworking applications where standard-length drills lack the reach required. The 27/64-inch (0.4219-inch) diameter and extended 145-millimeter flute length make it appropriate for production drilling in steel, stainless, cast iron, and similar materials. The right-hand spiral flute geometry and straight-cylindrical shank with 7/16-inch shank diameter allow direct mounting in standard drill chucks and collet systems. Through-coolant support makes it compatible with CNC machines equipped with internal coolant delivery.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• 140-degree point angle with X-thinned web reduces entry thrust and improves self-centering
• EgiAs finish coating for elevated heat and wear resistance during high-speed drilling
• Through-coolant capable for deep-hole chip evacuation and thermal control
• 10xD flute-to-diameter ratio supports extended reach in taper length applications
• Right-hand spiral flute with straight-cylindrical shank for broad machine compatibility

Compatibility

Designed as an OEM-style replacement or production tooling option for CNC machining centers and drill presses accepting a 7/16-inch straight-cylindrical shank. Compatible with machines equipped with internal through-coolant delivery systems.

Installation Notes

Installation and tool changes should be performed by qualified machinists or tooling technicians. Ensure the machine spindle is fully stopped and powered down before inserting or removing the drill. Verify shank seating depth and chuck or collet torque per the machine manufacturer's specifications before running. Confirm coolant line pressure and flow rate are appropriate for the drill before initiating a through-coolant cycle.
