IVY Classic Industries is dedicated to producing a comprehensive, quality line of power tool accessories and hand tools. IVY Classic ACR Insert and Power Bits are designed to withstand the high torque (rotational force) of impact drivers. High-grade S-2 tool steel is used for extra strength and durability. These ACR bits feature forged ribs that grip the screw and reduce cam-out stripping of screws and bits. The bits are heat treated and tempered to Rockwell Hardness 60-62 and the sandblasted finish prevents rust. IVY Classic Industries manufactures an extensive line of ACR insert and power bits.
