Description
Overview:
The Sealey HSS Fully Ground Drill Bit Set (Part No. AK4725) is a 25‐piece assortment of metric jobber‐length twist drills for accurate drilling in metal. Manufactured from high‐speed steel (HSS) to DIN 338, each bit is fully ground for consistent diameter, clean cutting and long service life. A 135° split‐point tip helps the bit start precisely with less wandering, reducing the need for centre punching. Suitable for use in standard 3‐jaw chucks on corded and cordless drills, as well as pillar drills and magnetic drills, this set is built for workshop, site and maintenance tasks. It is well suited to drilling stainless steel and copper, and offers reliable results on many everyday metalworking jobs in automotive, fabrication and construction settings.
Key Features:
- Fully ground HSS construction to DIN 338 for accuracy, strength and durability
- 135° split‐point tips for fast starts, reduced walking and improved control
- Optimised flute geometry for efficient swarf clearance and cooler cutting
- Performs well on stainless steel and copper when used at correct speeds and feeds
- Straight shanks fit standard keyless or keyed 3‐jaw chucks on hand and bench drills
- Re‐sharpenable cutting edges help extend service life and reduce consumable costs
- Organised storage case with clearly marked sizes for quick selection and safe transport
- Suitable for professional use and demanding DIY tasks where consistent hole quality is required
- Works best with appropriate cutting lubricant and correct RPM for the material
- 25‐piece coverage of common metric sizes for general maintenance and installation work
