## Summary description

DeWalt DT4929HHS is a 10-piece set of HSS cobalt metal drill bits sized 5 x 86 mm. Designed for drilling in hard metals and alloys, these high-speed steel bits with cobalt alloy provide improved heat resistance and wear durability. Suitable for workshop and industrial use with hand drills and drill presses for precision metalwork.

## Long description

DeWalt DT4929HHS cobalt HSS drill bit set contains ten identical 5 x 86 mm bits engineered for drilling into hard metals and alloys. These high-speed steel bits with a cobalt alloy offer increased heat resistance and wear durability compared with standard HSS, making them suitable for repeated and demanding metalworking tasks. The set is intended for use with hand drills and drill presses where precise, clean holes in steel, stainless steel and similar materials are required.
Advantages
The cobalt-enhanced HSS construction improves hardness and thermal stability, reducing bluntness when drilling at higher temperatures. Precision-ground flutes and tips deliver consistent cutting performance and accurate centring. Supplied as a 10-piece set of identical size, the kit ensures repeatable results and fast bit replacement during production or workshop use. The 86 mm overall length provides sufficient reach for most panel and plate thicknesses while maintaining rigidity.
Suitable for
Drilling holes in mild steel and alloy steels
Working with stainless steel and other heat-resistant metals
Precision metal fabrication in workshops and small-scale industrial settings
Use with hand-held drills and drill presses for through-holes and pilot holes
Key specifications
Drill bit type: high-speed steel (HSS) with cobalt alloy
Quantity: 10 pieces of the same size
Diameter: 5 mm
Overall length: 86 mm
Tip: precision-ground for accurate centring and cutting
Suitable materials: steels, stainless steels and similar hard metals
How to use
Select an appropriate drill speed and apply steady feed pressure while using cutting fluid or coolant when drilling stainless steel or other heat-sensitive materials. Secure the workpiece in a vice or clamp to prevent movement and ensure perpendicular alignment for accurate holes. Start with a pilot hole if required for deeper or larger-diameter follow-up operations. Replace worn bits promptly to maintain hole quality and avoid excessive heat build-up.
Usage recommendations
For best results, use moderate rotational speeds and a continuous supply of cutting lubricant when working at higher temperatures or on stainless steel. Inspect bits for wear and maintain sharpness by replacing rather than regrinding cobalt HSS bits to preserve geometry and performance.
