Drill bits set Dedra WITS19 — 19 pcs, steel, 135° point angle, for metal

Dedra WITS19 is a 19-piece steel drill bit set designed specifically for drilling metal. The bits have a 135° point angle which improves centering and reduces walking on harder surfaces, making them suitable for general metalworking tasks, maintenance and installation jobs. The set includes a range of sizes to cover common hole diameters used in repairs and fabrication where durable steel cutting edges are required.

Advantages

The drill bits are made of steel for strength and wear resistance during prolonged use on metal. A 135° point angle enhances bit stability and reduces the need for pilot holes on thin or hardened materials. The set format offers a comprehensive size range in one package, simplifying tool selection and reducing downtime. Each bit is ground to provide consistent cutting geometry for predictable hole quality.

Suitable for

• Drilling holes in mild and alloy steels
• Maintenance and repair work on metal components
• Installation of fasteners and anchors in metal structures
• Prototyping and workshop metal fabrication

Key specifications

• Quantity: 19 pieces
• Material: steel
• Point angle: 135° for improved centering
• Application: designed for drilling metal

How to use

Select the appropriate drill bit size for the required hole diameter and secure it in the drill chuck. Mark the drilling point and, where necessary, use a center punch to improve accuracy. Start at low speed to establish the hole, then increase speed according to material thickness and drill type. Apply steady, moderate pressure and use cutting fluid or lubricant when drilling thicker or harder metals to reduce heat and extend bit life. Remove chips regularly to prevent clogging.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. For best results, clamp the workpiece securely and use coolant when drilling high-strength or thick metals. Replace bits that show excessive wear or chipping to maintain hole quality and safety.
