Drill bits set Dedra WITS13, steel, 13 pcs, 135° point angle, for metal

Dedra WITS13 is a 13-piece steel drill bit set designed for reliable metalworking. The bits have a 135° point angle that reduces walking and improves centring when starting holes in harder materials. This set covers a range of commonly used diameters to support general workshop, maintenance and fabrication tasks where durable steel drill bits are needed.

Advantages

The 135° point angle provides improved tip stability and more accurate hole starts on metal compared with standard 118° bits. Manufactured from steel, the bits offer mechanical strength for routine drilling in a variety of ferrous and non-ferrous metals. The 13-piece assortment supplies multiple diameters so you can select the correct size for through-holes, clearance holes and pilot drilling. The set format keeps the bits together and accessible for workshop use.

Suitable for

• Drilling holes in steel, aluminium and other common metals
• Workshop maintenance and repair tasks
• Fabrication and assembly where multiple hole sizes are required
• Pilot drilling and clearance holes for bolts and fasteners

Key specifications

• Material: steel
• Number of pieces: 13
• Point angle: 135° for reduced walking and better centring
• Intended use: metal drilling
• Set range: assortment of common diameters for general metalworking

How to use

Select the drill bit diameter that matches the required hole size or pilot hole. Secure the workpiece and use an appropriate clamp or vice to prevent movement. Fit the bit in a compatible drill or drill press chuck, ensure the chuck is tightened, and set an appropriate speed for the material being drilled. Apply steady, moderate feed pressure and use cutting lubricant when drilling harder metals to extend bit life and improve hole quality. Withdraw the bit occasionally to clear chips and avoid overheating.

Usage recommendations

For best results when drilling metal, use cutting fluid, maintain correct drill speed for the material, and avoid excessive pressure that can cause premature wear. Inspect bits regularly for blunt edges or chipping and replace worn bits to maintain hole accuracy and reduce the risk of breakage.
