Drill Bit for Large Holes
This Drill America Silver and Deming bit cuts 1-19/64 inch diameter holes in metal. The high-speed steel body with surface-treated flutes resists wear during repetitive drilling. Its 1/2 inch reduced shank fits standard drill chucks while the 6 inch overall length provides reach for deeper workpieces. Industrial users and maintenance crews rely on this design for consistent results.
1/2 Inch Reduced Shank Decides Fit
The 1/2 inch reduced shank determines whether this bit mounts in your drill. Chucks smaller than 1/2 inch cannot hold it, so buyers with 3/8 inch capacity need a different tool. The 1.2969 inch decimal equivalent and 3 inch flute length define the cutting envelope, but shank compatibility is the gatekeeper. Verify your chuck size before ordering.
