8×D Length Ratio GARANT Master Steel Micro AlCrN Coated Solid Carbide Drill 0.8mm m7 DIN 6535 HA Straight Shank for Steel Micro Deep Hole CNC Drilling
Product Overview
The GARANT Master Steel Micro is a high-performance solid carbide micro drill with straight shank, manufactured in accordance with DIN 6535 HA standard and designed with 8×D flute length ratio. Adopting premium solid carbide blank and durable AlCrN multilayer coating, this micro drill features exceptional wear resistance, thermal stability and chip removal capacity. It delivers reliable and stable drilling performance for deep-hole machining on steel workpieces, suitable for continuous production on high-precision CNC machining centers and automatic drilling equipment.
The optimized flute geometry and point design ensure smooth chip evacuation and accurate hole positioning, maintaining tight dimensional tolerance and long service life for mass production of micro deep holes in steel components.
Key Features
High-quality solid tungsten carbide substrate provides superior rigidity and bending resistance, ideal for deep micro-hole drilling under high rotational speed.
Advanced AlCrN composite coating offers excellent high-temperature oxidation resistance and low friction, effectively reducing built-up edge and cutting heat.
Straight shank compliant with DIN 6535 HA standard for universal and stable clamping on standard tool holders and collets.
8×D length-to-diameter ratio design meets the requirements of deep hole drilling while balancing overall tool rigidity.
Precision ground drill point guarantees excellent positioning accuracy and straightness, preventing deviation during deep hole machining.
Tight m7 diameter tolerance ensures consistent hole size and interchangeability for assembly parts.
