Drill Bit Material

Drill bits may be made from a number of metals, each of which has advantages for specific applications. As the metal becomes more rigid, it also becomes more brittle and less able to be sharpened when it dulls. The table below summarises the characteristics of common drill bit materials and their preferred applications.

Drill Bit Material

General Characteristics

Preferred Applications

Low Carbon Steel Inexpensive, require sharpening or replacement Wood, soft plastics
Chrome Vanadium alloy or VA [1] Wood
High Carbon steel May lose temper and cutting edge if overheated Wood, metal
High Speed Steel or HSS Preferred among production workers because of ability to retain temper at very high speeds Wood, metal, plastics, most ceramics
Colbart Steel Alloy High performance and longevity; more brittle than HSS Metals including stainless steel
Titanium and Other Ceramic Coatings: Black oxide,  Titanium Aluminium Nitride, Titanium Carbon Nitride Give softer bits higher performance More difficult materials than base bit could handle
Tungsten Carbide and Carbide Tipped Strongest, hardest of all bits; all-carbide is very expensive; carbide-tipped is very effective at more reasonable price Virtually any material including stone
