Baildon DIN 338 RN NWKa Metal Drill Bit, 8.6 mm, HSS

The Baildon DIN 338 RN NWKa metal drill bit, with a diameter of 8.6 mm, is a professional-grade cutting tool engineered for high-performance drilling in various metal materials. Constructed from high-speed steel (HSS), this drill bit offers excellent heat resistance and structural integrity, ensuring consistent results during demanding drilling operations. Its design adheres to the DIN 338 standard, which defines the geometry and dimensions necessary for reliable, accurate hole creation in both ferrous and non-ferrous metals.

Advantages

This drill bit features a robust HSS construction that maintains its sharpness over extended periods of use, reducing the need for frequent replacements. The precision-ground geometry ensures efficient chip removal, which prevents clogging and overheating during the drilling process. By conforming to DIN 338 standards, the tool provides high dimensional accuracy, making it a dependable choice for tasks requiring tight tolerances and clean, burr-free holes in metal surfaces.

Suitable for

• Drilling holes in structural steel and iron
• Working with non-ferrous metals such as aluminum or copper
• Professional metalworking and fabrication tasks
• General maintenance and repair projects requiring precise metal drilling

When it may not be suitable

This drill bit is specifically optimized for metalworking and may not perform optimally when used on masonry, concrete, or extremely hard ceramic materials. Using it on materials outside its intended scope can lead to premature dulling of the cutting edges or damage to the tool.

Key specifications

• Diameter: 8.6 mm
• Material: High-speed steel (HSS)
• Standard: DIN 338
• Type: Twist drill bit

How to use

To achieve the best results, ensure the drill bit is securely fastened in the chuck of your power drill or drill press. Mark the center of the hole to be drilled and use a center punch to create a small indentation, which helps guide the bit and prevents it from wandering. Apply steady, moderate pressure while maintaining a consistent drilling speed appropriate for the material being worked. It is recommended to use a suitable cutting oil or lubricant to reduce friction and heat, which extends the life of the bit and improves the quality of the finish.

What to consider before purchase

• Verify that your drill chuck is compatible with the 8.6 mm shank diameter.
• Ensure the material you intend to drill is within the hardness range suitable for HSS tools.
• Consider the depth of the hole required to ensure the drill bit length is sufficient.

Usage recommendations

For optimal performance and longevity, always maintain a sharp cutting edge and use appropriate cooling lubricants when drilling through thick metal sections. Avoid excessive lateral pressure, which can cause the bit to snap.
