商品説明

IRWIN Tools 1792761 Speedbor Blue-Groove Wood Spade Bit Set, 17-Piece With Storage Case, provides every size standard length Speedbor spade bit in a durable storage case. IRWIN Blue-Groove Spade drill bits feature a patented Blue-Groove Point and cutting edge for faster chip removal and drilling speed. Double cutting spurs scribe the outside of the hole reducing breakout and delivering cleaner holes when through-hole drilling or countersinking. Plus, the bits have a thicker cutting edge and larger shank for improved durability and a longer cutting life. The 1/4' quick-change shank reduces slipping in standard chucks and is compatible with all 1/4' quick-change chucks, including impact drivers. This bit set comes in a durable molded plastic case for convenient storage and portability, and includes standard length bit sizes 1/4', 5/16', 3/8', 7/16', 1/2', 9/16', 5/8', 11/16', 3/4', 13/16', 7/8', 15/16', 1', 1-1/8', 1-1/4', 1-3/8', and 1-1/2'.
