Poranteräsarja Smart 11-KPL25 — HSS-metalli, 25-osainen

Smart 11-KPL25 is a 25-piece drill bit set designed for metalworking. The bits are made from high-speed steel (HSS) to provide durability and improved resistance to heat during drilling operations. This set includes a range of commonly used diameters suitable for workshop, maintenance and DIY tasks where accurate holes in metal and similar materials are required.

Advantages

The HSS construction ensures a balance of hardness and toughness for cutting metal, while maintaining heat resistance during prolonged drilling. A 25-piece assortment covers a broad span of frequently used hole diameters so users can select the appropriate size without frequent tool changes. The set’s organization and consistent bit geometry support repeatable drilling performance and straightforward replacement of worn bits.

How to use

Select the appropriate drill bit diameter for the required hole size and mount it securely in the drill chuck. Begin drilling at a moderate speed and apply steady, controlled pressure; for harder metals reduce speed and use cutting fluid or lubricant to control heat and improve chip evacuation. Retract the bit periodically on deeper holes to clear chips, and clamp the workpiece securely to prevent movement. After use, clean chips from the bits and store the set in its case to protect cutting edges.

Recommendations

For best results when drilling metal, use cutting oil or a suitable lubricant, adjust drill speed according to material hardness, and keep the drill axis perpendicular to the workpiece. Replace worn bits to maintain hole quality and safety.
