Description

The DT50050-QZ is a DEWALT 10-piece HSS-TiN (titanium nitride coated) shock-resistant metal drill bit set with a 1/4-inch hex shank, designed for use with impact drivers in metal drilling applications. The TiN coating provides a hard, friction-reducing surface that extends bit life and improves cutting efficiency compared to uncoated HSS bits.
The shock-resistant construction is specifically engineered to handle the high-frequency impact forces generated by impact drivers — unlike conventional twist drill bits that can fracture under impact. The 1/4-inch hex shank provides quick, tool-free bit changes and secure chuck engagement.
Suitable for drilling steel, aluminium, copper, and other metals with cordless impact drivers and drill drivers. Ideal for electrical and HVAC installation work where quick, metal drilling with an impact driver is required.
