Makita D-72229 1 - 10mmHSS-TiN Metal Drill Bit Set - 19 Pcs/Set

TiN coating lowers friction, improves heat resistance, and increases wear life, helping the bits stay sharper longer and drill more smoothly through metal.

Yes. While they are optimized for metal due to the HSS-TiN construction, the set is described as versatile enough for drilling into metal, wood, and plastic, making it a handy all-purpose set for various projects.

The 135° split point tip reduces walking or wandering when starting a hole, allowing for a cleaner, more accurate hole without the need for a pilot hole in many materials.

The round shank design is compatible with a wide range of drill chucks found on standard drills. You should verify that your drill’s chuck can accommodate the bit size and shank diameter included in the set.

Secure your workpiece with a clamp, choose the appropriate bit size, start at a low speed, apply steady, light pressure, and allow the TiN-coated HSS to cut smoothly. Use cutting fluid or light lubrication when drilling metal to reduce heat build-up, and avoid forcing the bit.

Keep bits clean and dry between uses, avoid overheating by running at appropriate speeds, use lubrication when drilling metal, and store them in the provided case to prevent nicks and corrosion. A cool-down period between heavy drilling jobs can also help prolong life.

After use, wipe bits clean, dry them completely, and return them to the provided storage case. Store in a dry environment to prevent corrosion, and avoid dropping or banging the bits, which can nick the tips.

Wear safety glasses, secure the workpiece with clamps, keep hands clear of the rotating bit, avoid excessive force, use appropriate drilling speed, and manage heat with lubrication or coolant. Let the bit do the cutting rather than forcing it.

Identify the target hole diameter needed for your project, select the corresponding bit size from 1.0 mm to 10.0 mm in 0.5 mm steps, and consider starting with a smaller pilot hole if drilling thicker metal. The 135° split point helps with accurate starts even in harder materials.

Fepy generally offers returns within a standard window for unused items in original packaging; if you’re not satisfied, initiate a return following the store’s policy guidelines. Always keep the packaging and receipts until you’ve confirmed the product meets your needs.

For best results, pair this set with a compatible drill that supports standard round-shank bits and a chuck that can accommodate the bit sizes.
