FAQs
Are these bits compatible with standard power drills?
Yes, they fit most standard corded and cordless drill chucks.
Can I use these for masonry or concrete?
No, these are HSS drill bits intended for metals, wood, and plastics; they will not effectively cut concrete or stone.
What is the benefit of the DIN 338 standard?
DIN 338 is a standard that ensures the bits meet specific geometric requirements for length, shank diameter, and overall performance.
How do I store the bits properly?
The set includes a protective storage tube; ensure all bits are wiped clean and dry before placing them back in the tube to prevent rust.
Do I need to use cutting fluid?
While not always necessary, using cutting fluid when drilling through steel or iron will significantly extend the life of the bit and prevent overheating.
Troubleshooting
Bit slipping in the drill chuck
Ensure the drill chuck is tightened evenly; if the bit is coated in oil, wipe the shank clean before insertion.
Bit getting stuck in the material
Retract the bit while the drill is running to clear the flutes of debris; consider using a light cutting oil for metal applications.
Hole is oversized or messy
Check that the drill is set to high speed and apply steady, light pressure to maintain alignment.

Setup, Compatibility & Care
To begin, ensure your power drill chuck is fully tightened to prevent bit slippage. These bits are compatible with standard corded and cordless drills. To maximize the lifespan of your bits, avoid excessive pressure; let the sharpness of the steel do the work. After use, wipe away metal shavings or dust with a dry cloth to prevent corrosion. Store them in the provided tube away from moisture to ensure the HSS steel remains in top condition for your next project.
