Drill America 1" HSS Silver and Deming Bit

This Drill America bit is a Silver and Deming style drill accessory built for high-speed steel drilling tasks. Its reduced shank fits 1/2 inch chucks while the 3-flatted design prevents slippage during heavy feed pressure. The tool targets machinists and maintenance technicians who need a large-diameter hole in metal using standard drill presses or heavy-duty handheld drills.

Surface-treated flutes with 3-flatted reduced shank

The flutes receive a surface treatment that reduces friction and helps clear chips during deep cuts. A 1/2 inch reduced shank with three flats locks securely in a chuck without the need for a specialised collet. Flute length of 3 inches and overall length of 6 inches allow reach into workpieces while keeping the shank engaged. Builders needing a bit larger than 1 inch or a straight shank for a different chuck size will need another tool.
