Ø15.8 mm 3XD solid carbide (VHM) drill bit DIN 6537 – advanced machining of hardened steels
Ø15.8 mm carbide drill bit made of cemented carbide to DIN 6537 is designed for drilling hardened and stainless steels. The 140° point angle prevents the cutting edge from wandering when starting a hole. Solid carbide (VHM) drill bit 15.8 allows holes to be produced to H7 tolerance on CNC machining centers.
Key technical parameters of the 3xD drill bit
- Maximum radial runout 0.05 mm – manufacturing to DIN 6537 ensures straightness when drilling in hydraulic chucks, shrink-fit holders, and ER collets
- Specialized 140° angle – the cutting edge optimized for 1.4301 stainless steel, heat-resistant alloys, and titanium ensures stable positioning without spot drilling
- Protective layer resistant to temperatures up to 850° – the coating extends tool life by 200 percent compared with uncoated drills and reduces chip adhesion in acid-resistant steel
- Flute length 47.4 mm at a diameter of 15.8 mm – the 3xD ratio increases structural rigidity during machining on CNC milling centers and lathes
- Self-centering solid carbide cutting edge – manufactured to DIN 6537, reduces cycle time by 35 percent by eliminating the need for spot drilling in production
15.8 mm 3XD carbide drill bit is used in facilities performing precision machining on CNC machines. Combining tool holders with a maximum runout of 0.05 mm and appropriate drilling parameters ensures dimensional repeatability in structural and hardened steels.
Frequently asked questions
A tolerance of H7 can be achieved on CNC machines equipped with tool holders with a maximum runout of 0.05 mm. Rigid workpiece clamping and cutting parameters matched to the material type are essential.
ER collets are a suitable solution for carbide drill bits. They ensure clamping accuracy with radial runout up to 0.05 mm. The disadvantage is the lack of through-body coolant capability, 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 eliminates cutting edge slippage when starting to drill hard materials.
