## Long description

DeWalt DT70787-QZ is a spiral cutting drill bit made from ground high-speed steel (HSS-G) designed for general-purpose drilling in metals and other hard materials. The spiral flute geometry supports efficient chip evacuation while the ground cutting edges deliver consistent performance and extended wear resistance. Intended for use with hand-held and bench drills, this HSS-G drill bit suits workshop and construction environments where reliable hole quality and tool life are important.
Advantages
The ground high-speed steel construction provides a precise cutting edge and improved hardness compared with rolled equivalents, reducing burrs and improving hole finish. Spiral flutes remove chips effectively during drilling to prevent clogging and overheating. The robust HSS-G material offers good wear resistance and dimensional stability under typical drilling loads, making the bit suitable for repetitive use and varied metalworking tasks.
Suitable for
Drilling holes in steel and non-ferrous metals
Workshop and maintenance drilling tasks
Construction site general-purpose drilling
Use with corded and cordless drills as well as drill presses
Key specifications
Material: ground high-speed steel (HSS-G)
Cut type: spiral flute for efficient chip evacuation
Intended use: general-purpose metal drilling
Compatibility: standard drill chucks on hand-held and bench drills
How to use
Secure the drill bit in the drill chuck and tighten firmly before starting. Select an appropriate drilling speed and, if drilling metals, use cutting fluid or lubricant to reduce heat and extend tool life. Apply steady axial pressure and allow the spiral flutes to evacuate chips; withdraw periodically for deeper holes to clear swarf. After use, clean chips from the flutes and store the bit in a dry location to prevent corrosion and preserve cutting performance.
Usage recommendations
Choose speeds and lubrication appropriate for the material being drilled, avoid excessive side load or twisting, and inspect the cutting edge regularly. Replace the bit when wear or chipping affects hole quality to maintain consistent drilling results.
