Total TAC100303 3MM Drill Bit

Key materials include a tungsten carbide tip for durability and a heat-treated chromium molybdenum steel shank for strength. The coating is bronze oxide to reduce heat buildup, and the flute design is symmetrical for faster chip removal. The standard shank size is 1/8", ensuring compatibility with most drill chucks.

Yes. The tungsten carbide tip handles metal and wood effectively, while the bit’s design also works well on other common construction materials like plastic. For best results, match speed and feed to the material and avoid overheating.

This drill bit uses a standard 1/8" shank, which fits most drill chucks. If you’re unsure about size, confirm your drill accepts 1/8" shanks before use.

For metal, start at a slow to medium speed with steady, moderate pressure to prevent overheating. For wood, you can use higher feed rates but still avoid excessive heat. Maintain steady pressure, let the bit cut, and withdraw chips frequently to prevent binding.

Open your drill chuck slightly, insert the 1/8" shank fully, and tighten securely to minimize runout. Use a steady drilling pace, avoid side pressure, and start on scrap material to verify alignment before proceeding with your actual work.

Carbide-tipped bits are highly durable and typically don’t require frequent sharpening. If you notice a loss of performance, inspect for damage and replace if the edge is chipped or dull. Keep the bit clean and dry, and store in a protective case to prevent edge damage.

Wear eye protection and gloves as needed, secure the workpiece with clamps, ensure the drill is off when mounting or changing bits, and avoid overheating by using appropriate speeds and lubrication if drilling metal. Keep loose clothing and hair away from the drill bit.
