## Summary description

DeWalt DT4904-QZ twist drill bit set consisting of 2 pieces in a blister pack. Designed for right-hand rotation drills, these twist drill bits are intended for general drilling tasks. Supplied as a two-piece set for use with compatible drilling tools to create holes in applicable materials using standard rotary drilling methods.

## Long description

DeWalt DT4904-QZ twist drill bit set consists of two right-hand rotation bits supplied in a blister pack for general drilling tasks. Manufactured for drilling portable or stationary, these HSS-Co (high speed steel with 5% cobalt) twist drills are designed to cut metals with high alloy content and tensile strengths up to 1100 N/mm², including heat- and acid-proof steels, cast iron, bronze, welded seams, stainless and chrome-nickel steels. The set combines reinforced core construction, an optimised tip and flute geometry, and non-slip shanks to deliver improved penetration, chip evacuation and tool life for compatible drilling tools.
Advantages
The 5% cobalt content preserves a sharper cutting edge and provides substantially longer life compared with standard HSS-R bits. An optimised tip with a recessed cutting wing reduces burrs and aids cleaner, more accurate holes while a ‘no-walk’ tip facilitates initial penetration on surfaces 5 mm and above. Spin-proof three-sided shanks on applicable diameters improve grip in the chuck and reduce slipping during use. The thicker central core towards the chuck increases fracture stability during freehand drilling and the flute design accelerates chip removal and reduces heat build-up for faster drilling.
Suitable for
Drilling high-alloy steels and stainless steels up to 1100 N/mm² tensile strength
Working on cast iron, bronze and welded seams
Portable and stationary drilling in metal fabrication and maintenance
Applications requiring burr-reduced, accurate holes in metal
Key specifications
Set contents: 2 twist drill bits in blister pack
Rotation: right-hand
Material: high speed steel with 5% cobalt (HSS-Co)
Recommended workpiece tensile strength: up to 1100 N/mm²
Features: no-walk tip, recessed cutting wings, optimised flute geometry
Shank: three-sided, anti-slip design on applicable diameters
Construction: reinforced central core increasing in thickness towards the chuck
How to use
Select the correct drill bit diameter for the required hole and secure it in the drill chuck, ensuring the anti-slip shank seats fully if applicable. Use right-hand rotation and an appropriate feed rate for the material. For hard, high-alloy steels and stainless materials, use steady pressure, adequate cooling or cutting fluid as appropriate, and avoid excessive speed to reduce wear and overheating. Start drilling with the no-walk tip to position the bit, then proceed with continuous rotary motion and allow the flutes to evacuate chips. Periodically withdraw the bit to clear chips and allow cooling during deeper or prolonged drilling operations.
Usage recommendations
For best results when drilling metals with high alloy content, use cutting fluid or coolant, secure the workpiece, and operate the drill at speeds and feed rates appropriate for HSS-Co bits. Inspect the bit regularly for wear and replace when the cutting edge degrades to maintain hole quality and reduce the risk of breakage.
