Drill bit Proline 5.0 mm HSS, set of 2 pcs, model 5153630

Drill bit Proline 5.0 mm HSS, set of 2 pcs, model 5153630 — two high-speed steel (HSS) twist drill bits designed for metalworking. Each bit has a 5.0 mm diameter, a working length of 52 mm and an overall length of 86 mm. The bits feature a 135° point angle with adjustable chisel/slip geometry for improved cutting performance on various metals.

Advantages

Made from high-quality HSS steel for improved heat resistance and longer life when drilling metal. The 135° point angle reduces walking and provides better centring on metal surfaces. The dimensions (5.0 mm diameter, 52 mm working length, 86 mm overall length) suit standard metal drilling tasks. Sold as a set of two, offering immediate replacement and extended use.

Suitable for

• Drilling holes in steel and other ferrous metals
• Metal fabrication and maintenance work
• Workshop and home workshop metalworking tasks

How to use

Mark the drilling point and secure the workpiece in a vice or clamp to prevent movement. Use an appropriate drill chuck and set the drill speed according to the metal type and bit diameter — typically moderate to low speeds for harder steels. Apply steady, even pressure and allow the bit to cut; withdraw periodically to clear chips and reduce heat. Use cutting fluid or lubricant when drilling tougher or thicker metals to extend bit life and improve hole quality.

Usage recommendations

For best results, pre-centre holes with a centre punch when drilling thin sheet or when precise positioning is required. Store bits dry and protected to prevent corrosion; resharpen HSS bits when cutting performance decreases.
