## Summary description

DeWalt DT4915-QZ is a single twist drill bit supplied in a blister pack for right-hand rotation use. Designed for drilling with compatible drills, the package contains one piece and is intended for general drilling tasks where a standard right-hand twist bit is required. Suitable for workshop and construction applications.

## Long description

DeWalt DT4915-QZ is a single right-hand twist drill bit supplied in a blister pack, intended for general workshop and construction drilling of steels and other high-alloy metals. Manufactured with 5% cobalt HSS for extended life and an optimised tip and flute geometry, this drill bit is designed for accurate, burr-free holes and improved penetration performance when used with compatible portable or stationary drills.
Advantages
The cobalt-enriched high-speed steel composition provides greater hardness and maintains a sharper cutting edge, delivering significantly longer service life compared with standard HSS-R bits. A no-walk tip enables easier centreing and penetration on a variety of surfaces from 5 mm diameter upwards, while recessed cutting wings produce cleaner holes with reduced burrs. Size markings are placed away from abrasion zones for clear readability. A three-sided no-slip shank improves grip in the chuck for diameters 5 mm and above, and a strengthened central core increases fracture resistance in freehand use. Optimised flute and tip geometry accelerates penetration and improves chip evacuation, lowering heat build-up during drilling.
Suitable for
 Portable and stationary drilling of high-alloy steels and metals
 Work on heat- and acid-resistant steels, stainless and chrome-nickel steels
 Drilling cast iron, bronze and welded seams
 General workshop and construction drilling tasks requiring durable HSS-cobalt bits
Key specifications
 Type: right-hand twist drill bit
 Material: high-speed steel with cobalt alloying (5% cobalt)
 Pack: single piece in blister pack
 Tip design: no-walk tip for easier penetration and reduced walking
 Shank: three-sided no-slip shank for improved chuck grip (applies to diameters from 5 mm)
 Core: reinforced central core for increased fracture stability (applies to larger diameters)
 Performance: optimised flute and tip geometry for faster penetration and improved chip removal
How to use
Secure the bit firmly in a compatible drill chuck, ensuring the three-sided shank is seated correctly if applicable. Align the no-walk tip at the desired drilling point; for improved accuracy on smooth surfaces start with a centre punch or pilot mark. Use appropriate cutting speed and feed for the material being drilled and apply steady pressure—avoid excessive force that may cause premature wear. Use coolant or cutting fluid when drilling stainless or high-alloy steels to reduce heat build-up and extend tool life. After use, clean swarf from the flutes and store the bit in a dry place to prevent corrosion.
Usage recommendations
Use cutting fluid for prolonged drilling sessions in stainless and heat-resistant steels. For diameters 5 mm and above, rely on the no-slip shank for stable clamping; for smaller diameters verify chuck grip and consider using a pilot hole when drilling hardened surfaces.
