Drill bit Dedra WMST0420, steel, 135° point angle, for metal, 1 pc

Single Dedra WMST0420 drill bit made of steel, designed specifically for drilling into metal. The bit has a 135° point angle that helps with centring and reduces walking on hard surfaces, making it suitable for a range of metalworking, maintenance and repair tasks. Supplied as one piece and intended for use with compatible hand drills and drill presses, it provides a straightforward solution for creating precise holes in sheet metal, plates and other ferrous and non-ferrous metal components.

Advantages

The 135° point angle improves tip stability and reduces the tendency to skate on the workpiece, aiding accurate hole starts. Manufactured from steel, the bit balances cost and durability for general-purpose metal drilling. Its single-piece supply allows easy replacement and inventory control for workshop use. The geometry is optimized for common drilling speeds and clamping conditions encountered in maintenance and repair environments.

Suitable for

• Drilling holes in sheet metal and metal plates
• Maintenance and repair tasks in workshops and garages
• General-purpose metalworking and fabrication
• Preparation of pilot holes for tapping and fastening

Key specifications

• Material: steel
• Point angle: 135° for improved centring
• Application: metal drilling
• Quantity: 1 piece
• Suitable for use with hand drills and drill presses

How to use

Secure the workpiece firmly using clamps or a vice to prevent movement. Fit the drill bit into the drill chuck and tighten securely. Use appropriate cutting speed and feed for the metal type—slower speeds for harder metals—and apply steady, even pressure. For improved performance and tool life, use cutting fluid or lubricant when drilling thicker or harder materials. Clear chips regularly and withdraw the bit periodically to avoid overheating and bit breakage.

Usage recommendations

For best results on harder metals, start with a small pilot hole and increase to the required diameter, and always use cutting fluid to reduce heat and wear. Inspect the drill bit for wear or mushrooming of the tip before use and replace if damaged.
