## Long description

Proline 77225 — 25-piece general-purpose drill bits is a compact set of metal-cutting tools designed for routine drilling tasks in workshops, construction sites and home projects. The set contains 25 drill bits produced entirely by grinding from refined high-speed steel, offering enhanced resistance to torsional stress. Bits feature a 135° point angle with chamfering adjustment for improved centering and reduced walking on a variety of materials, and the set is arranged for convenient storage and easy selection for standard drills.
Advantages
The drill bits are made by precision grinding from high-grade high-speed steel, which increases edge accuracy and improves wear resistance under repeated use. A 135° point angle combined with chamfering adjustment provides stable centering and efficient chip evacuation on many workpieces. The material and manufacturing method deliver higher torsional strength, reducing the risk of breakage during heavy or intermittent loads. The compact case keeps all 25 pieces organized for quick access and transport.
Suitable for
General household repairs and DIY drilling into metal, wood and plastics
Routine maintenance and workshop tasks requiring a range of drill sizes
Construction site tasks where a reliable set of standard drill bits is needed
Preparedness kits for mechanics, handymen and hobbyists
Key specifications
Set composition: 25 drill bits covering common sizes for general-purpose drilling
Manufacturing: bits produced entirely by grinding for precise geometry
Material: refined high-speed steel with elevated resistance to torsional stress
Point design: 135° point angle with chamfering adjustment for improved centering
Compatibility: intended for use with standard corded and cordless drills
Storage: compact organized case for easy selection and transport
How to use
Select a drill bit size appropriate for the hole required and insert it securely into the drill chuck, ensuring proper clamping and alignment. Begin drilling at low speed to establish the hole and maintain steady pressure; increase speed as appropriate for the material. Use cutting fluid when drilling metals to reduce heat and prolong bit life. After use, clean chips from the flutes and return bits to the storage case to prevent corrosion and maintain organization.
Usage recommendations
For improved accuracy on smooth surfaces, mark the drilling point and use a center punch before drilling. When working with metal, apply cutting oil and avoid excessive feed pressure to reduce wear. Replace excessively worn or damaged bits to maintain consistent hole quality and safe operation.
