Drill Bit DEDRA WMST0638 1 pc Steel 135° Point Angle for Metal

The Dedra WMST0638 drill bit is a single steel cutting tool engineered for drilling metal. With a 135° point angle and a robust steel construction, this drill bit is intended to provide accurate hole placement and stable cutting action when working with a range of ferrous and non-ferrous metals. The design focuses on straight drilling and reduced walking at the start, making it suitable for general metalworking tasks and repair jobs.

Advantages

This steel drill bit features a 135° point angle that improves centering and reduces the tendency to wander on smooth metal surfaces. Its solid steel construction offers wear resistance and dependable rigidity during cutting, which helps maintain hole geometry and extends usable life under normal workshop conditions. As a single-piece bit, it is straightforward to mount in standard chucks and suitable for use with hand drills and drill presses.

Suitable for

• Drilling holes in sheet metal and thicker metal plates
• General metal fabrication and maintenance work
• Preparing pilot holes for tapping or fastening
• Use with portable drills and bench drill presses

Key specifications

• Material: steel
• Point angle: 135°
• Quantity: 1 piece
• Intended application: metal drilling

How to use

Secure the drill bit in an appropriate chuck, ensuring it is centered and tightened. Select a drilling speed appropriate for the type and thickness of the metal being worked; lower speeds are recommended for harder materials. Use cutting fluid or coolant when drilling to reduce heat and extend bit life. Begin drilling with light pressure to establish the hole, then apply steady, moderate pressure until the hole is complete. Clear swarf frequently to maintain cutting efficiency.

Usage recommendations

For best results, match drill speed and feed to the metal type, keep the bit cooled with cutting fluid, and replace the bit when signs of dulling or chipping appear to avoid poor hole quality and excessive heat generation.
