Catalog number: AMD3S-4.2 Features: ●3-piece set of cushion drills (for metalworking). ●Dramatically reduced core vibration allows for high-speed drilling. ●Good bite, no need for a punch (marking to determine the center of the hole so that the tip of the drill does not escape). ●(Used for 3.0 mm or more where it is effective.●)●High hardness HSS (high speed steel) maintains a sharp cutting edge. ●The cushion drill is integrated with a grooved drill shaft by pressing. ●(To increase the bonding strength, 2-sided cuts are added for 1.8 mm or more for further reinforcement.●)In addition, the resin ring suppresses core vibration and rattling, allowing for accurate drilling. ●The flute angle of the end drill is processed to be gentle from the tip to the base (shank side), so cutting chips are discharged smoothly and holes can be drilled at high speed. Applications: ●For drilling various holes in iron, light metals, synthetic resins, wood, etc., and for drilling pilot holes for tapping. Specifications: ●Set contents (mm): 4.2 x 3 pieces ●Shank diameter (mm): 6.35 ●Total length (mm): 108 ●Compatible with 18V ●6.35mm hexagonal shaft type ●X-shaped thinning (φ3.0mm or more) Material/Finish: ●High-speed steel HSS (high speed steel) Caution: ●Please check the correct application, size, and usage before use. ●The drill will become hot immediately after drilling and there is a risk of burns, so please be careful. ●Firmly secure the workpiece and press the drill at a right angle to the workpiece. ●Do not use it by applying impact with an impact driver. ●Please be careful not to damage the drill or scatter cutting chips.
