## Summary description

DeWalt DT4911-QZ twist drill bit designed for drilling with right-hand rotation. Supplied as a single-piece blister pack, this drill bit fits standard drill applications requiring a rotating cutting tip. Intended for use with drilling tools to create holes; suitable where a single, replaceable twist drill is needed.

## Long description

DeWalt DT4911-QZ twist drill bit designed for right-hand rotation and supplied as a single-piece blister pack. Engineered for drilling a wide range of steels and metals, this solid high-speed twist drill features a cobalt-enriched composition and optimized geometry to deliver improved cutting life, faster penetration and reliable hole quality in demanding materials.
Advantages
The 5% cobalt content preserves a sharper cutting edge and extends tool life up to four times compared with standard HSS-R drills. A no-walk tip provides accurate positioning and easier penetration on surfaces from 5 mm diameter upwards, producing cleaner, burr-free holes thanks to recessed cutting wings. A spin-proof three-sided shank on sizes 5 mm and above ensures a secure grip in chucks, while an increasing central core thickness toward the shank improves fracture resistance for freehand use on diameters 4.8 mm and up. Optimized tip and flute geometry increases penetration speed and debris evacuation, reducing heat build-up during drilling.
Suitable for
Portable or stationary drilling of high-alloy steels and metals
Drilling heat- and acid-resistant steels, stainless and chrome-nickel alloys
Working with cast iron, bronze and welded seams
Applications requiring single replacement twist drill bits
Key specifications
Rotation: right-hand
Material: high-speed steel with 5% cobalt
Tip type: no-walk (self-centering) tip for easier penetration
Shank: three-sided anti-slip shank on diameters 5 mm and above
Core design: reinforced central core increasing in thickness toward shank (from 4.8 mm)
Packaging: single piece blister pack
Suitable tensile strength of workpiece material: up to 1100 N/mm²
Performance: improved penetration speed and debris removal versus standard HSS-R
How to use
Select a drill speed and feed appropriate for the workpiece material and secure the DeWalt DT4911-QZ firmly in the drill chuck, ensuring the three-sided shank (if present for the chosen diameter) seats correctly. Position the no-walk tip on the intended drilling point and start at a moderate speed to establish the hole; increase speed as cutting stabilizes. Use cutting fluid on stainless, heat- or acid-resistant steels to reduce heat and prolong tool life. Withdraw periodically to clear chips when drilling deep holes and allow the bit to cool if it becomes hot.
Usage recommendations
For best results, match drill speed and lubrication to the material type, maintain firm but controlled feed pressure and replace the bit when edge wear reduces cutting performance. Use a center punch for highly polished surfaces to aid initial penetration.
