Introduction

• DM flow-drill bits create long, durable threads without producing chips. The standard version forms a raised bushing, while the flat version removes the ridge for a smooth surface. These tools excel in stainless steel, copper, and mild steel. Common uses include heat exchangers, welded metal frames, bearing mounts, furniture hardware, bicycle components, and various industrial metal structures.

  
  

  

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.
