Harvey Tool CXZ0625-C3 Micro Drill Bit 1/16 in Carbide

Product Description

The HARVEY TOOL CXZ0625-C3 is a solid carbide micro drill bit designed for high-performance deep-hole drilling in demanding machining applications. It features a 140-degree split point, a spiral flute geometry, and an AlTiN (aluminum titanium nitride) coating that extends tool life in hard and abrasive workpiece materials. The through-coolant design delivers cutting fluid directly to the tip, reducing heat buildup and helping clear chips in deep-hole operations. At 1/16 inch (0.0625 inch) diameter with an h6 diameter tolerance, this bit is built for precision work where dimensional accuracy is critical. It is part of the Harvey Tool Miniature High Performance Drills - Deep Hole Coolant-Through series.

This drill bit is suited for CNC machining centers and precision drilling operations in aerospace, medical device, mold and die, and general metalworking environments. The 3.00 mm shank diameter and 75 mm overall length make it compatible with standard collet toolholding systems. The right-hand cut spiral flute configuration is the industry-standard orientation for most production drilling setups. Applications include stainless steel, hardened steel, titanium, and other difficult-to-machine alloys where tool life and hole quality are priorities for machinists and tool and die professionals.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating reduces friction and extends tool life at elevated cutting temperatures
• Through-coolant design delivers coolant directly to the cutting edge for deep-hole drilling
• 140-degree point angle reduces thrust force and improves centering on entry
• h6 shank diameter tolerance ensures consistent, accurate toolholder fit
• Spiral flute geometry promotes efficient chip evacuation

Compatibility

Part of the Harvey Tool Miniature High Performance Drills - Deep Hole Coolant-Through series. Fits standard collet-style toolholders sized for a 3.00 mm shank diameter with through-coolant capability.

Installation Notes

Installation and use should be performed by qualified machinists familiar with CNC toolholding and speeds-and-feeds selection for solid carbide micro drills. Verify that the machine spindle supports through-coolant delivery before use, as dry running a through-coolant drill can reduce tool life significantly. Secure the 3.00 mm shank in a precision collet or hydraulic chuck rated for the shank diameter to minimize runout. Follow the machine tool manufacturer guidelines for RPM and feed rate when working with small-diameter carbide tooling to avoid breakage.
