Kennametal 4149634 Taper Length Drill Bit 7/32 in

Product Description

The KENNAMETAL 4149634 is a taper length twist drill bit designed for precision hole-making in metalworking and machining applications. Built to a 7/32 inch diameter with an overall length of 94 millimeters, this bit offers extended reach compared to a jobber-length drill while maintaining rigidity. The shank diameter measures 6.00 millimeters for secure chuck engagement. Manufactured in material grade KC7325, a carbide-based cutting grade engineered for wear resistance and thermal stability in demanding drilling operations. Maximum drilling depth is 48.00 millimeters. This is a single-piece unit appropriate for CNC machining centers, drill presses, and manual machine setups.

The 4149634 is suited for production and maintenance machining environments where consistent hole quality and tool life are priorities. The taper length design provides additional flute length over jobber bits, making it a common choice when drilling through thicker stock or when clearance for chips and coolant flow is needed. Machinists and tool-room technicians working with ferrous metals, alloys, and similar materials will find this drill appropriate for through-hole and blind-hole work within its rated depth capacity.

Key Features

• 7/32 inch cutting diameter for precise hole sizing
• Taper length geometry provides extended reach beyond standard jobber-length drills
• KC7325 carbide material grade for enhanced wear resistance and heat tolerance
• 6.00 millimeter shank diameter for secure chuck or collet clamping
• Maximum drilling depth of 48.00 millimeters supports through-hole and blind-hole applications
• 94 millimeter overall length balances reach with cutting stability

Compatibility

Designed as an OEM-style replacement and standard cutting tool for use in drill presses, CNC machining centers, and manual mills or lathes accepting a 6.00 millimeter shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify chuck or collet size matches the 6.00 millimeter shank before clamping. Apply appropriate cutting fluid or coolant for the workpiece material to maximize tool life and hole quality.
