Drill America Solid Carbide Bit

This Drill America DMOD1/2-1 is a solid carbide drill bit built for abrasive materials such as cast iron, non-ferrous alloys, high-silicon aluminium, copper, plastics, bronze, hard rubber and plexiglass. It serves machinists and fabricators who need consistent hole accuracy in high-temperature drilling applications where standard steel bits wear quickly. The bright, uncoated finish keeps the cutting geometry sharp for clean entry in these specific workpiece types.

Round Shank and Spiral Flute Fit

The 1/2 inch round shank fits standard drill chucks and collets without requiring a specialised holder, while the 3 inch flute length clears chips efficiently during deep-hole work. At 4-3/4 inches overall length the bit reaches into recessed features without needing an extension, freeing the operator from extra setup time. The 118 degree conventional point centres reliably on flat surfaces and reduces walk on the materials listed.

Uncoated Finish for Material Control

The bright uncoated surface prevents coating buildup that can alter hole tolerance in soft or gummy plastics and non-ferrous alloys. No bundled software or accessories are included; the bit itself is the complete tooling solution. Buyers who need coated performance for steel or titanium, or who require a shank style other than round, should select a different drill bit.

Questions about this item

How deep can the 3" flute cut before chips clog the hole?

The 3" flute length is the effective drilling depth; beyond that chips cannot clear and the bit will bind.

Does the uncoated bright finish run hotter than coated bits during all-day drilling?

Without a coating the bright finish has higher friction, so sustained high-speed use generates more heat than coated alternatives.

What shank size must my drill chuck accept for this 1/2" bit?

The round shank matches the 1/2" cutting diameter, so a chuck that opens to at least 1/2" is required.
