## Long description

Proline 78225 — 25 pieces, mixed sizes, metal and wood drilling is a compact drill bit set intended for general-purpose drilling into wood and metal. The set contains a selection of common bit diameters suitable for use with both cordless and corded drills. Each bit is made entirely by grinding from high-class HSS steel with 5% cobalt, featuring a 135° point angle with chamfering adjustment to ensure controlled penetration and reduced walking on the work surface.
Advantages
The drill bits are manufactured from high-class HSS with 5% cobalt for improved hardness and heat resistance during prolonged use. Fully ground construction delivers consistent geometry and cutting edges for accurate drilling. A 135° point angle with chamfering adjustment provides better centring and smoother start on metal and wood, while the cobalt alloy increases life span compared with standard HSS bits. The compact 25-piece assortment covers everyday sizes, reducing the need to switch tools during common repair, carpentry and workshop tasks.
Suitable for
 Drilling holes in soft and hard wood for joinery and carpentry
 Drilling through steel sheets, mild steel and non-ferrous metals
 General household repairs and installation tasks
 Light workshop and hobby projects requiring a range of common bit sizes
Key specifications
 Set size: 25 pieces in mixed diameters suitable for wood and metal
 Material: High-speed steel (HSS) with 5% cobalt
 Manufacturing method: Fully ground drill bits for precise geometry
 Point geometry: 135° point angle with chamfering adjustment for improved centring
 Compatibility: Suitable for use with corded and cordless drills
How to use
Select a drill bit size appropriate for the hole diameter required and secure it firmly in the drill chuck. Use a suitable drill speed and feed for the material being drilled: moderate speeds and steady pressure for metal, higher speeds for softer woods. For metal, consider using cutting fluid or lubricant to reduce heat build-up and extend bit life. Ensure the workpiece is clamped or supported to prevent movement and wear appropriate personal protective equipment, such as safety glasses.
Usage recommendations
For best results on metal, start with a small pilot hole if drilling a large diameter and apply cutting fluid. When drilling wood, avoid excessive pressure; let the bit cut at its designed pace. Store bits in a protective case and inspect cutting edges for wear before use to maintain accuracy and safety.
