DREMEL Precision Drill Bit Set (628) - 2615062832

The Dremel 628 is an essential kit for anyone needing to drill extremely accurate holes in various types of materials. This set of 7 drill bits has been designed to ensure maximum efficiency with rotary multi-tools, offering a versatile solution for both model making and minor technical maintenance.

Technical Specifications and Materials

The drill bits included in the set are made of high-speed steel (HSS). This metallic composition is essential for maintaining sharpness over time and resisting the high temperatures generated during rotation. Although optimized for small diameter holes, using these Dremel bits for mild steel and non-ferrous metals ensures clean cuts and reduces the risk of accessory breakage.

Recommended Applications

The Dremel 628 set is ideal in contexts where millimeter precision is an essential requirement. The bits perform particularly well on the following materials:

• Light metals: aluminum, copper, and brass.

• Steel: precision drilling on thin sheets of mild steel.

• Wood: pilot holes in hardwoods and softwoods without splintering.

• Plastics: plexiglass, PVC, and resins, minimizing the risk of material melting.

Set Contents and Dimensions

To ensure maximum operational flexibility, the kit includes 7 different sizes, all stored in a practical protective case for easy organization and transport.

Included accessory diameters:

• 0.8 mm

• 1.2 mm

• 1.6 mm

• 2.0 mm

• 2.4 mm

• 2.8 mm

• 3.2 mm (compatible with standard Dremel collet)

Tips for optimal use

To prolong the life of Dremel bits for steel and hard materials, it is advisable to use a moderate speed and, if necessary, a cutting lubricant. It is also essential to ensure that the keyless chuck or collet is properly tightened to avoid vibrations that could compromise drilling precision.
