Mueller Kueps 244 808 Spot Welding Drill Bit HSSE-TICN 8 x 80 mm

Key Facts

• HSSE spot weld drill bit with TiCN (Titanium Carbon Nitride) PVD coating
• 8 mm diameter and extended 80 mm length for deeper reach applications
• Designed for high cutting speeds and long service life
• Optimized for interrupted cuts such as spot weld removal
• Suitable for demanding use on hardened steel and layered materials

Overview

This HSSE-TiCN Spot Welding Drill Bit (8 x 80 mm) is designed for efficient removal of spot welds in automotive repair, metal fabrication, and industrial maintenance. The extended 80 mm length provides additional reach for deeper or hard-to-access weld points, while maintaining precision and stability during operation.

Constructed from HSSE (high-speed steel with cobalt), the bit offers excellent heat resistance and strength. The TiCN PVD coating enhances surface hardness, reduces friction, and significantly extends tool life, making it ideal for repeated use in demanding environments. It performs reliably in interrupted cutting conditions commonly encountered in spot weld drilling.

Category FAQs

• What is a spot weld drill bit used for?
  It is designed to remove spot welds while preserving the underlying metal layers.
• What are the advantages of TiCN coating?
  TiCN coating increases hardness, reduces friction, and improves wear resistance for longer tool life.
• Why choose HSSE material?
  HSSE provides enhanced heat resistance and durability compared to standard high-speed steel.
• What are interrupted cuts?
  Interrupted cuts occur when the tool repeatedly engages and disengages the material, such as when drilling spot welds.
• Is this suitable for hardened steel?
  Yes, it is suitable for use on hardened steel and high-strength alloys.
• Does the longer length affect performance?
  The extended length allows better reach while maintaining cutting stability when used properly.
• Is coolant recommended?
  Yes, using coolant helps extend tool life and improves cutting efficiency.
• How do I select the correct size?
  Choose a diameter that matches the spot weld size and application requirements.
