1-1/32" HSS Silver and Deming Drill Bit
The Drill America bit is a high-speed steel Silver and Deming drill with a 1-1/32 inch cutting diameter. Its 1/2 inch reduced shank allows use in standard drill chucks that cannot accept larger straight shanks. Surface-treated flutes improve chip evacuation and reduce friction during drilling operations.
Practical limits of the 1/2" reduced shank
The 1/2 inch shank fits common three-jaw chucks but transmits less torque than a full-diameter shank, so heavy feed pressure can cause slippage. The 3 inch flute length and 6 inch overall length restrict the maximum hole depth to roughly the flute length. The decimal equivalent of 1.0312 inches confirms the exact size for precision layout work.

Questions about this item
Should I pick the 1-1/32 inch Silver and Deming bit or a different diameter for my half-inch chuck?
This bit has a 1/2 inch reduced shank that fits a standard half-inch drill chuck; choose it when you need a 1.0312 inch hole.
What does the 3 inch flute length mean when the bit is in the drill press?
The 3 inch flute gives you that much clear cutting depth before chips must be cleared, while the 6 inch overall length keeps the shank securely gripped.
