Drill bit FANAR Wiertło węglikowy Ø4.00 mm, length 36/74 mm, 5xD, HA6 VHM, AT IK, MASTERDRILL DIN 6537

Solid carbide drill bit FANAR Wiertło, Ø4.00 mm with working/overall lengths of 36/74 mm, is manufactured to DIN 6537 and designed for precise metal drilling in machine tools and CNC equipment. The tool is specified as 5xD and features HA6 geometry to support stable cutting and repeatable hole quality. The VHM (solid carbide) construction provides high rigidity and wear resistance while the AT IK surface finish improves chip evacuation and tool life in demanding high-speed and conventional machining operations.

Advantages

The FANAR Wiertło carbide drill delivers consistent concentricity and dimensional accuracy due to its DIN 6537 shank and precise tip geometry. Solid carbide construction offers enhanced stiffness and thermal resistance compared with high-speed steel alternatives, enabling higher cutting speeds and longer tool life on abrasive or hard materials. The HA6 geometry promotes stable cutting with reduced tendency to chatter, and the AT IK finish assists in smoother chip flow and lower built-up edge formation, which together support repeatable hole quality in series production.

Suitable for

• Precision drilling of steel, alloyed steels and cast materials on CNC machines
• High-speed drilling where carbide tooling is required
• Through-hole and standard depth holes up to 5xD for production runs
• Metalworking applications in jigs, fixtures and automated machining centers

How to use

Mount the drill securely in an appropriate collet or chuck compatible with DIN 6537 shanks. Select cutting speed and feed rates suitable for solid carbide tooling and the workpiece material, using recommended coolant or internal/external lubrication for improved chip evacuation and tool life. Start drilling with moderate feed to establish the hole and then continue with steady feed rates; retract periodically if chip clogging occurs. Ensure proper machine rigidity and minimal spindle runout to maintain hole accuracy and avoid premature tool wear.

Usage recommendations

For best results, use this solid carbide drill in rigid setups, with stable clamping and appropriate coolant. Adjust speed and feed based on material hardness—lower speeds for harder alloys and higher speeds for non-ferrous materials—while keeping feeds proportional to diameter. Inspect holes for burrs and tool wear periodically during production runs and replace the tool when concentricity or surface finish deteriorates.
