The Dapetz HSS Metric Jobber Drill Bits (10mm) are ideal for DIY enthusiasts and professionals who require a reliable, high-speed steel tool for drilling into diverse materials like steel, aluminum, and wood. Engineered to DIN338 standards, these bits offer excellent durability and precision for general-purpose workshop tasks; however, they require careful speed management and lubrication to maximize their service life when working with tougher metals.

These bits are crafted from HSS-R 4341 high-speed steel.
While they can work on soft metals, HSS-R bits are not specifically optimized for the high work-hardening nature of stainless steel. Use low speeds and plenty of coolant if attempting this.
The bit features a 118-degree point angle, which is standard for general-purpose drilling.
Like all steel drill bits, this will eventually dull with use. It can be resharpened using a drill bit sharpening tool or bench grinder.
Yes, as long as your drill chuck is capable of holding a 10mm diameter shank.
Reduce the drill speed and apply a cutting fluid or cooling agent to the drilling area.
Use a center punch to create a small indentation before starting, or use a smaller pilot bit first.
Check that the bit is securely seated in the chuck and ensure the material is clamped down tightly.
To ensure the longevity of your drill bit, always secure the workpiece firmly before beginning to drill. Since this is a 10mm bit, ensure your power tool's chuck is capable of accepting 10mm shanks or larger.
Care instructions include cleaning the bit after each use to remove metal shavings or resin buildup. Store the bits in a dry environment—such as a drill index or original packaging—to prevent oxidation. If the bit becomes dull, it can be resharpened using a proper bench grinder jig set to the standard 118-degree angle.
