IRWIN 1837629 POWER BIT IMPACT T30 X 3-1/2"OAL BU

IRWIN Impact Performance Series fastener drive bits are engineered for maximum durability and long life with impact drivers.  These power bits are designed with precision tip geometry  so they fit fasteners more precisely, which reduces stripping and cam-out.  Manufactured with heavy-duty, cold-forged, high-grade steel, they'll withstand extremely high torque output, and the black oxide finish resists corrosion and increases the life of the bit. They're designed with a 1/4" quick-change shank, so they work with all types of impact and rotary drivers.  Plus, they also have a unique Power Groove design for use with the exclusive IRWIN Magnetic Collar Attachment, which prevents fasteners from slipping and wobbling.Built for maximum durability and long life with impact driversPrecision tip geometry delivers superior fitment, reducing stripping and cam-outPower Groove designed for compatibility with IRWIN Impact Performance Series Magnetic Screw-Hold AttachmentManufactured with heavy-duty, cold-forged, high-grade steel to withstand high torque outputBlack oxide finish resists corrosion and increases life of bit1/4" quick-change shank is designed to work with impact drivers, and reduces slipping in standard drill chucks*Square and Phillips bits only**vs. standard screwdriver bitsSpecificationsItem #DescriptionPoint SizeShank DiameterOverall Length1837494TORX Impact Power Bits (1-pc)T101/4"2"1838510TORX Impact Power Bits (10-pc Bag)T101/4"2"1837495TORX Impact Power Bits (10-pc)T101/4"2"1837522TORX Impact Power Bits (1-pc)T101/4"6"1838511TORX Impact Power Bits (10-pc Bag)T101/4"6"1837523TORX Impact Power Bits (10-pc)T101/4"6"1837496TORX Impact Power Bits (1-pc)T151/4"2"1838512TORX Impact Power Bits (10-pc Bag)T151/4"2"1837497TORX Impact Power Bits (10-pc)T151/4"2"1837510TORX Impact Power Bits (1-pc)T151/4"2-3/4"1837511TORX Impact Power Bits (10-pc)T151/4"2-3/4"1837516TORX Impact Power Bits (1-pc)T151/4"3-1/2"1838513TORX Impact Power Bits (10-pc Bag)T151/4"3-1/2"1837517TORX
