Drill bit FANAR W9-604X13-0650, solid carbide, diameter 6.50 mm, 34/79 mm, 3xD, HA6, X-DRILL (DIN 6537)

Solid carbide drill bit FANAR W9-604X13-0650 is a precision tool designed for metalworking and machining operations requiring high rigidity and wear resistance. With a 6.50 mm diameter and a total/working length configuration of 34/79 mm, this 3xD drill conforms to DIN 6537 and features HA6 geometry combined with the X-DRILL flute design to enhance chip evacuation and positional accuracy. The tool is intended for both through and blind hole drilling where carbide performance yields longer tool life and consistent hole quality.

Advantages

The solid carbide construction delivers high hardness and thermal stability, which improves wear resistance and dimensional stability during extended runs. HA6 geometry provides a controlled cutting edge for stable chip formation, while the X-DRILL flute profile supports efficient chip evacuation and reduces the risk of clogging. The 3xD ratio balances reach and stiffness, offering reliable straightness and concentricity in standard drilling depths.

Suitable for

• Drilling through holes and blind holes in steel, stainless steel, and non-ferrous alloys
• High-precision machining where hole tolerance and surface finish matter
• CNC drilling and automated production runs requiring consistent repeatability
• Applications that demand carbide tooling for improved tool life under higher cutting speeds

Key specifications

• Material: solid carbide
• Diameter: 6.50 mm
• Overall/working length: 79 mm / 34 mm
• Drilling depth: 3xD (three times the diameter)
• Geometry: HA6
• Flute design: X-DRILL for enhanced chip evacuation
• Standard: manufactured to DIN 6537

How to use

Select appropriate spindle speed and feed based on workpiece material, machine rigidity and coolant usage; start with recommended carbide cutting data for the specific alloy being machined. Secure the workpiece and use a suitable rigid toolholder to minimise runout. For through holes, maintain continuous feed and coolant to assist chip removal; for blind holes, reduce peck depth or use peck drilling cycles if chips accumulate. Inspect holes and tool condition periodically and replace the drill when wear affects hole quality.

Usage recommendations

Use cutting fluid or internal/external coolant where possible to extend tool life and improve surface finish. Monitor runout and replace worn holders to preserve concentricity. For stainless steels and tougher alloys, reduce cutting speed and increase feed per revolution within carbide tool limits to avoid built-up edge and premature wear.
