Botek General-purpose machine tool gun drill, blade diameter 8 mm, B110-080390, 1 piece

Catalog number: B110-080390 Features: ● Gun drill that can efficiently drill deep holes on general-purpose machines such as machining centers and NC lathes. ● Since machining is performed using pilot holes (guide holes), guide bushes and guide plates are not required. ● The oil hole is either two holes (blade diameter 7.5 mm or more) or kidney-shaped (blade diameter 7.0 mm or less), so the amount of cutting oil discharged is large and the discharge of cutting chips is excellent. ● If you use a horizontal general-purpose machine tool, you can process with low cutting oil pressure (around 1.0 MPa). Applications: ● Workpiece: Carbon steel, alloy steel, stainless steel, tempered steel, cast iron, aluminum alloy, heat-resistant steel. Specifications: ● Blade diameter (mm): 8 ● Total length (mm): 390 ● Maximum machining depth (mm): 260 ● Driver (diameter x length) (mm): 20 x 50 ● Carbide head brazed type Material / Finish: ● Carbide alloy (K15)
