Drill America No 48 solid carbide drill bit

The Drill America DMOD48 is a solid carbide drill bit designed for precision drilling in abrasive and high-temperature applications. It is suited for machinists and technicians who must maintain hole accuracy when working with cast iron, non-ferrous alloys, high-silicon aluminium, copper, plastics, bronze, hard rubber or plexiglass. The carbide construction resists wear far longer than standard high-speed steel in these materials.

Installation and common issues

The bit installs like any standard twist drill in a compatible chuck or collet; ensure the holder runs true to prevent carbide chipping. Because carbide is brittle, excessive feed pressure, misalignment or interrupted cuts will cause the cutting edges to fracture rather than dull gradually. Always use rigid setups and appropriate coolant or air blast to clear chips and control heat.

Capacity and headroom

This drill handles the listed abrasive materials comfortably while holding tight tolerances in repetitive production. It runs out of effective life when used on ferrous steels harder than its design range or when the machine spindle lacks the rigidity to prevent vibration. The solid carbide body cannot be resharpened economically once the cutting edges are worn or damaged.

Questions about this item

How can I verify the No 48 drill bit is cutting cleanly in cast iron after setup?

Check for consistent chip formation and a smooth hole wall without chatter marks when drilling cast iron or non-ferrous alloys.

Does the DMOD48 package include any collets or coolant accessories, or must they be purchased separately?

The box contains only the solid carbide drill bit; collets, holders and coolant systems are sold separately.

Which Drill America solid carbide size should I choose for high-temperature drilling in high-silicon aluminum?

Select the No 48 bit when the application demands maintained accuracy in abrasive, high-temperature materials such as high-silicon aluminum.
