Dremel MAX Precision Drill Bit Set 628DM

This set is suitable for drilling into metal, plastic, wood, and drywall. It is best for softer metals and lighter applications.

The recommended speed range for these bits is 20,000 to 30,000 RPM.

After use, wipe the bits clean with a cloth to remove debris. Store them in the provided case to prevent damage.

All drill bits in this set have a 3.2mm shank diameter, ensuring compatibility with most Dremel multi-tools.

These bits are designed for softer metals, wood, and plastics. They are not intended for drilling into hard steel or other very hard materials.

The Dremel 628DM set includes seven multipurpose drill bits.

The set includes drill bits ranging in size from 0.8mm to 3.2mm.

Ensure you are using the correct speed (20,000-30,000 RPM) for the material. Apply lighter pressure and avoid forcing the bit. Check if the bit is appropriate for the material hardness.

Verify that the tool speed is within the recommended range. Clean any debris from the bit and the material. Ensure the bit is sharp and not worn out. For plastics, a slightly lower speed within the recommended range might help prevent melting.

Ensure the 3.2mm shank is properly seated in the collet or chuck. Tighten the collet securely according to your tool's manual. Check the collet for any damage or debris.

Reduce the drilling pressure and speed slightly within the recommended range. Ensure the bit is clean and free of debris. For extended use, consider intermittent drilling with cooling periods.
