Drill bit Dedra WMST0412, steel, 135° point angle, for metal, 1 pc

Single Dedra WMST0412 drill bit made of steel with a 135° point angle, designed for drilling metal. The bit features standard twist-drill geometry suitable for producing through-holes and general metalworking operations. Supplied as one piece, this steel drill bit is intended for workshop, repair and maintenance tasks that require drilling in mild and some hardened steels.

Advantages

The steel construction provides durability for routine metal drilling and the 135° point angle reduces walking on the workpiece when starting holes in metal surfaces. Standard twist-flute geometry promotes efficient chip evacuation and stable cutting action during through-hole drilling. Supplied individually, the single-piece format is convenient for replacing worn tools or stocking common sizes without excess packaging.

Suitable for

• Drilling through-holes in mild steel and similar ferrous materials
• Repair and maintenance tasks in workshops and fabrication environments
• General-purpose metal drilling with hand-held or drill-press equipment

Key specifications

• Material: steel
• Point angle: 135°
• Flute type: standard twist
• Intended material: metal (including mild and some hardened steels)
• Pack quantity: 1 piece

How to use

Secure the workpiece and select an appropriate clamping method to prevent movement. Fit the drill bit into a compatible chuck, ensuring it is centred and tightened. For metal drilling, mark the drill position and consider using a centre punch to help locate the bit. Start drilling at low speed to establish the hole, then increase speed as appropriate for the material and diameter. Apply steady pressure and pause occasionally to clear chips and avoid overheating; use cutting fluid or lubricant for improved life and finish when drilling steel.

Usage recommendations

Use suitable personal protective equipment, clamp the workpiece firmly, and choose drill speeds and lubrication appropriate to the metal type and bit diameter to maximise tool life and hole quality.
