SUGOGIRE KYOKKOU Coating Drill Series — Achieving Ultimate Durability and Speed —
Maximize Work Efficiency and Reduce Costs
On-site drilling demands both efficiency and precision. The SUGOGIRE KYOKKOU Coating Drill Series features cobalt high-speed steel enhanced with KYOKKOU coating (TiAlCN: Titanium Aluminum Carbon Nitride), dramatically improving surface hardness, heat resistance, wear resistance, and anti-adhesion properties. This results in long-lasting, stable performance that maximizes work efficiency and contributes to cost reduction.
GLOBAL SAW SUGOGIRE STEP DRILL SDR & STEP LESS DRILL DDR
GLOBAL SAW SUGOGIRE STEP DRILL SDR
With a steep spiral groove design and a sharp rake angle, this step drill provides exceptional drilling speed.
The XR thinning at the cutting edge ensures stable drilling performance by securely biting into the material.
Made of cobalt high-speed steel (HSS-Co) with Kyokko coating (TiAlCN: Titanium Aluminum Carbonitride), it offers greatly improved hardness, heat resistance, wear resistance, and anti-adhesion properties, resulting in an extended tool life.
GLOBAL SAW SUGOGIRE STEPLESS DRILL DDR
The stepless design eliminates level differences, reducing resistance and enabling faster drilling compared to conventional step drills.
The XR thinning at the cutting edge ensures stable drilling by firmly engaging with the material.
Made of cobalt high-speed steel (HSS-Co) with Kyokko coating (TiAlCN: Titanium Aluminum Carbonitride), it provides significantly enhanced hardness, heat resistance, wear resistance, and anti-adhesion properties for long service life.
