Drill bit FANAR W9-604X13-0420 carbide Ø4.20 mm, 24/66 mm, 3xD, HA6, X-DRILL (DIN 6537)

Solid carbide drill bit FANAR W9-604X13-0420 with a 4.20 mm cutting diameter is designed for precision holemaking in a variety of metalworking applications. The tool has a working length of 24 mm and overall length of 66 mm, providing a 3xD length ratio. Manufactured to DIN 6537 and HA6 tolerance with X-DRILL geometry, this carbide drill bit is suitable for use in drilling machines and CNC equipment for both through and blind holes where rigid runout control and repeatable hole quality are required.

Advantages

The solid carbide construction delivers high rigidity and wear resistance for consistent cutting performance and prolonged tool life. X-DRILL geometry improves centring and chip evacuation, reducing deflection and the tendency to wander at small diameters. HA6 tolerance ensures precise diameter control and repeatable hole accuracy, while the 3xD length ratio balances reach and stiffness to suit standard drilling operations in metal.

Suitable for

• Precision drilling of steel and non-ferrous metals
• Through holes and blind holes in CNC machining
• Production environments requiring tight dimensional tolerance and repeatable hole quality
• Drilling operations with rigid tool holding and runout control

How to use

Mount the carbide drill securely in an appropriate collet or chuck with minimal runout. Select cutting speeds and feeds compatible with carbide tools and the workpiece material; use coolant or cutting fluid when recommended for the material and operation. For best results, use steady feed and avoid excessive pecking on through-hole applications unless chip control requires intermittent withdrawal. Inspect hole diameter and surface finish after drilling and replace the tool when wear or chipping affects hole quality.

Usage recommendations

Use precise toolholding and verify spindle runout before machining. For hardened or abrasive materials, reduce cutting speed and increase feed per revolution within carbide limits. Maintain appropriate coolant flow for chip evacuation and tool life extension.
