[Features] ●By thinning the candle-shaped carbide tip and the cutting edge, the work material can be drilled sharply, and the drilling speed has been improved. ●The center point of the tip of the carbide tip exhibits outstanding positioning performance, enabling drilling of holes close to a perfect circle. ●The center point suppresses core vibration during drilling and reduces the vibration burden during work.
[Use] ●Work material: Concrete, block, mortar, Japanese wall.
