Drill bit FANAR WIERTLO WEGLIK Ø8.60 mm, length 47/89 mm, 3xD, VHM, HA10, X-DRILL DIN 6537

Solid carbide drill bit FANAR WIERTLO WEGLIK Ø8.60 mm with a working length of 47 mm and overall length of 89 mm. Manufactured to DIN 6537 with a 3xD length, HA10 geometry and X-DRILL point, this VHM (solid carbide) tool is made for precise, stable drilling in metal. It is intended for use in machine tools and stationary drilling rigs where dimensional accuracy, repeatability and edge retention are required.

Advantages

The tool combines solid carbide construction with HA10 geometry to deliver high rigidity, low deflection and consistent hole quality. The X-DRILL point reduces walking at the start of the cut and improves centring, while the 3xD length balances reach and stiffness for typical through-hole and shallow blind-hole applications. The design promotes long tool life and predictable wear when used with appropriate speeds, feeds and coolant.

Suitable for

• Precision drilling in steel and alloyed metals
• Machine-tool drilling operations and CNC machining
• Stationary drilling rigs and production runs requiring repeatable hole diameters
• Through-holes and shallow blind holes up to three times the diameter

Key specifications

• Material: solid carbide (VHM)
• Diameter: 8.60 mm
• Working length: 47 mm
• Overall length: 89 mm
• Drill point: X-DRILL point for improved centring
• Geometry: HA10 for high rigidity and chip control
• Length ratio: 3xD (three times diameter)
• Standard: manufactured to DIN 6537

How to use

Secure the drill in the appropriate tool holder or chuck with correct clamping length to minimize runout. Select cutting speed and feed according to workpiece material, carbide tool recommendations and machine rigidity. Use cutting fluid or internal/external coolant as required to control temperature and evacuate chips. Start drilling with light feed until the X-DRILL point has established a stable centre, then continue at the recommended feed for the diameter and material. Retract periodically in deeper holes to clear chips if necessary.

Usage recommendations

For best results, use rigid fixturing and minimal overhang to reduce bending. Match speeds and feeds to carbide tool guidelines for the specific metal being machined; increase coolant flow for alloyed steels and interrupted cuts. Inspect holes for burrs and finish, and replace the tool when dimensional accuracy or surface quality degrades.
