Drill bits set Dedra WITS25 — 25 pcs, steel, 135° point angle, for metal

Dedra WITS25 is a 25-piece steel drill bit set with a 135° point angle designed specifically for drilling metal. The set includes a range of twist drill sizes suitable for general metalworking, repair and maintenance tasks, and workshop use. The bits are intended for use in standard drill chucks compatible with steel twist drills and offer a practical selection for everyday metal drilling needs.

Advantages

The Dedra WITS25 set combines a comprehensive range of sizes in a single compact kit, reducing the need to purchase individual bits. Steel construction provides good hardness and wear resistance for routine metal drilling. The 135° point angle improves centering on flat metal surfaces and reduces walking, allowing more accurate hole positioning when starting holes in sheet metal or plate. The set is compatible with common drill chucks and can be used with corded and cordless drills that accept standard twist drills.

Suitable for

• General metalworking and fabrication
• Maintenance and repair tasks on machinery and equipment
• Workshop projects involving steel, iron, and non-hardened metals
• Drilling holes for fasteners, rivets and fittings

Key specifications

• Number of pieces: 25
• Material: steel twist drills
• Point angle: 135°
• Intended use: drilling metal and similar materials
• Compatibility: standard drill chucks for twist drills

How to use

Select the appropriate drill size from the Dedra WITS25 set and secure the bit in the drill chuck, ensuring it is tightened correctly. Mark the drilling point on the workpiece and, if necessary, use a center punch to improve accuracy. Start drilling at low speed to establish the hole, then increase speed as appropriate for the material and bit size while applying steady, moderate feed pressure. Use cutting fluid or coolant when drilling thicker or harder metal to reduce heat and extend bit life. After use, clean the bits and store them in the provided case or designated storage to prevent corrosion and damage.

Usage recommendations

For best results when drilling metal, use a center punch for accurate starts, apply cutting fluid to reduce heat and wear, and avoid excessive pressure or high speeds that can dull the steel bits. Match drill speed to material thickness and bit diameter and store the set dry to maintain performance.
