Carbide drill bit Ø11.8 mm 3XD solid carbide (VHM) DIN 6537 HA – precision machining of hardened steel
Ø11.8 mm carbide drill bit made from cemented carbide to DIN 6537 is designed for machining hardened and stainless steels. The 140° point angle ensures stable centering and eliminates slipping on the surface. Solid carbide (VHM) drill bit 11.8 enables holes to be produced to an H7 tolerance on CNC machines.
Technical characteristics of the 3xD carbide drill bit
- Precision runout of no more than 0.05 mm – manufactured to DIN 6537, ensures axial alignment during drilling in hydraulic chucks, shrink-fit holders, and ER collets
- Specialized 140° geometry – the cutting edge optimized for 1.4301 stainless steel, heat-resistant alloys, and titanium eliminates the need for preliminary spot drilling
- Protective layer withstanding 850°C – the coating increases tool life by 200 percent compared with uncoated drill bits and reduces chip adhesion in acid-resistant steel
- Flute length 35.4 mm at a diameter of 11.8 mm – the 3xD ratio ensures structural rigidity during machining on CNC milling centers and lathes
- Self-centering solid carbide construction – manufactured to DIN 6537, reduces cycle time by 35 percent by eliminating the spot drilling operation in production
11.8 mm 3XD carbide drill bit is used in facilities performing precision machining on CNC machines. Combining tool holders with runout up to 0.05 mm and appropriate drilling conditions ensures dimensional repeatability in structural and hardened steels.
Frequently asked questions
An H7 tolerance can be achieved on CNC machines with a tool holder with runout up to 0.05 mm. Secure workpiece clamping and cutting parameters appropriate for the material type are necessary.
ER collets are a suitable solution for carbide drill bits. They ensure clamping accuracy with runout up to 0.05 mm. The disadvantage remains the lack of internal coolant delivery, but the versatility of ER allows flexible use with different diameters.
This geometry is designed for stainless steel grades 1.4301 and 1.4404, steel hardened to 55 HRC, heat-resistant alloys, and Grade 5 titanium. The angle prevents cutting edge slippage when starting to drill hard materials.
