Mitsubishi MQS WSTAR steel and cast iron machining solid carbide drill 5D internal oil supply type 10.9 mm DP3020 MQS1090X5DB 1 piece

Catalog number: MQS1090X5DB Features: ●A new lineup of WSTAR drill series specialized for steel and cast iron machining. ●The new material "DP3020" achieves more than twice the tool life of conventional products in steel and cast iron machining. ●The adoption of triple margins improves guideability and suppresses damage to the margins by purifying the coolant flow, allowing for excellent machining hole accuracy to be maintained. ●The new coolant hole shape (TRI Cooling Technology [R-up]) improves the cooling and lubrication efficiency of the cutting edge, and is particularly effective in MQL machining. Applications: ●Cutting materials: carbon steel, alloy steel, cast iron. Specifications: ●Blade diameter (mm): 10.9 ●Groove length (mm): 77 ●Total length (mm): 134 ●Shank diameter (mm): 11 ●Effective machining depth: 5D (blade diameter x 5 times) ●Surface treatment: Ultra-multilayer PVD coating (DP3020) Material/Finish: ●Ultra-fine particle cemented carbide (UWC)
