## Summary description

DeWalt DT4916-QZ is a single twist drill bit designed for right-hand rotation. Supplied in a blister pack, this 1-piece drill bit is intended for drilling operations that use standard rotary drilling tools. It suits users needing a spare or replacement twist bit for general-purpose drilling tasks with compatible drills.

## Long description

DeWalt DT4916-QZ is a single twist drill bit designed for right-hand rotation and supplied as one piece in a blister pack. It is intended for use with standard portable or stationary rotary drills and engineered for drilling high-alloy steels and a range of metals with tensile strength up to 1100 N/mm², including heat- and acid-proof steel, cast iron, bronze, welded seams, stainless and chrome-nickel steels. The drill bit incorporates a no-walk tip and recessed cutting wings to improve initial penetration and produce cleaner, more accurate, burr-free holes.
Advantages
The 5% cobalt content maintains a sharper cutting edge and provides longer tool life compared with standard HSS-R bits. An optimised tip and flute geometry increases penetration speed and removes swarf efficiently, reducing heat buildup during drilling. The three-sided anti-slip shank improves grip in the chuck for diameters 5 mm and above, while a progressively thicker central core towards the chuck enhances fracture stability in freehand use for larger diameters.
Suitable for
Drilling heat- and acid-resistant steels and stainless steels
Drilling cast iron and bronze
Metal fabrication and maintenance tasks requiring durable twist bits
Portable and stationary drilling operations on high-strength alloys (up to 1100 N/mm²)
Key specifications

Shank: Hex shank for secure chuck engagement (spin-proof 3-sided grip on diameters 5 mm and above)
Finish: Gold-coloured coating
Pack quantity: 1 piece in blister pack
How to use
Install the DeWalt DT4916-QZ twist drill bit into a compatible drill chuck or hex bit holder, ensuring the shank is seated securely. Select an appropriate rotational speed and feed rate for the base material and the 1.2 cm diameter bit; use slower speeds for stainless and high-alloy steels to limit heat buildup. Begin drilling with light pressure to allow the no-walk tip to locate the hole, then increase steady pressure as the bit penetrates. Withdraw periodically to clear chips when drilling deep holes and apply cutting fluid where recommended for the specific material.
Usage recommendations
For best results on stainless and high-alloy steels, use coolant or cutting fluid, maintain moderate speeds, and avoid excessive axial force. Inspect the bit for wear before use and replace when cutting performance or hole quality degrades.
