Designed for quick conversion between hammer drilling and standard drilling tasks in workshop or home use. Premium Material Construction: Crafted from chrome- steel and carbon steel for high hardness, strength, and excellent abrasion resistance. The robust build ensures long service life, stable performance under heavy duty operation, and reliable clamping even in demanding applications. Classic 3-Jaw High Clamping Force Design: Traditional 3-jaw drill chuck provides stronger, more uniform clamping force on round-shank drill bits.
