The "Multi Drill MDH Type" is a carbide-coated drill for processing steel and cast iron. The wide chip pocket smoothly discharges chips and reduces resistance, achieving stable processing even under high-efficiency conditions. Additionally, the optimized cutting edge shape suppresses stress concentration, minimizing damage even during high-efficiency processing with high cutting edge loads. 【Features】 ■ RP Shinning that maximizes low resistance ■ HF coating that achieves excellent wear resistance and heat resistance *For more details, please refer to the PDF document or feel free to contact us.

The "SEC-Sumi Dual Mill DMSL/DMSW type" is a high-efficiency roughing cutter designed for ultra-high feed rates and large depths of cut. With its complex arc-shaped cutting edge, it achieves both a small cutting angle and a large depth of cut. It enables high-efficiency machining with a feed rate of up to 3.5 mm/t per edge. Additionally, even in high-feed machining with a feed rate of 2.0 mm/t or more per edge, it achieves good surface roughness without the need for a wiper insert. 【Features】 ■ Achieves both a small cutting angle and a large depth of cut simultaneously with a complex arc-shaped cutting edge ■ Enables high-efficiency machining with a feed rate of up to 3.5 mm/t per edge ■ Controls cutting resistance in the direction of back force due to the small cutting angle ■ Stable machining even with long tool overhang without chatter ■ Introduction of DMSL type for small diameters ■ Lineup includes cutting diameters from Φ16mm and above *For more details, please refer to the PDF document or feel free to contact us.
