Introduction

• Designed for precision, DM thermal drill bits are offered in standard and flat styles. Standard bits generate a strong collar for tapping, while flat bits remove excess material for a level finish. They deliver chip-free machining, reliable thread strength, and outstanding tool longevity. Perfect for automotive, aerospace, metal furniture, heating systems, lighting equipment, and cooling-tube fabrication.

  
  

  

Key benefits

• How to Select the Right Thermal Flow Drill Bit

  Thermal flow drill bits are divided into Standard (Round) and Flat-Cut (Planed) versions.

  Standard Round: Creates a drawn-out bushing and leaves a raised ring.

  Flat-Cut: Forms the same bushing but mills off the raised ring for a flush surface.
