The Astro Pneumatic 401K3 is a 3-piece heavy duty air hammer bit set engineered for use with the highest power air hammers. Each bit is manufactured from Astro's proprietary THOR hammer alloy, a material specifically developed to deliver superior hardness and exceptional toughness in demanding hammering applications. Unlike conventional bits that sacrifice durability for hardness, the THOR alloy achieves both, dramatically reducing chips, cracks, and premature wear. This set provides three versatile bit lengths to handle a wide range of professional applications with confidence.
