Titanium Coated HSS Drill Bit Set Metric Thread M3-M10 Countersink
Titanium Coated HSS Drill Bit Set Metric Thread M3-M10 Countersink
Titanium Coated HSS Drill Bit Set — Metric Thread M3-M10
Upgrade your workshop with this professional-grade 6-piece Titanium Coated HSS Drill Bit Set. Engineered for precision threading and countersinking across metric sizes M3 through M10, these high-speed steel bits are built for demanding tasks — from DIY home projects to professional metalworking and woodworking applications.
Why Choose Titanium-Coated HSS Bits?
- Titanium Nitride (TiN) Coating: The golden titanium coating dramatically increases surface hardness, reduces friction, and extends bit life compared to standard uncoated HSS bits.
- High-Speed Steel (HSS) Core: HSS construction maintains cutting performance even at elevated temperatures, making these bits suitable for drilling metal, wood, plastic, and composite materials.
- Metric Thread Coverage (M3–M10): The set spans the most commonly used metric fastener sizes, giving you a versatile range for tapping, threading, and countersinking in a single kit.
- Countersink Design: Integrated countersink geometry lets you create clean, flush screw seats in one step — no separate tool required.
- Precision Ground Flutes: Precision-machined flutes ensure efficient chip evacuation and accurate, burr-free holes every time.
- Universal Shank Compatibility: Fits standard drill chucks and drill presses — ready to use straight out of the box.

Frequently Asked Questions
Q: What materials can the Titanium Coated HSS Drill Bit Set M3-M10 be used on?
A: These titanium-coated HSS drill bits are versatile enough for use on metal (including mild steel and aluminum), wood, plastic, and composite materials. The titanium nitride coating provides added hardness that is especially effective when working with harder metals compared to standard HSS bits.
Q: What is the advantage of a titanium coating on HSS drill bits?
A: The titanium nitride (TiN) coating increases surface hardness, significantly reduces friction between the bit and material, and helps the cutting edge stay sharp longer. This means faster drilling, cleaner holes, and a longer overall tool lifespan compared to uncoated high-speed steel bits.
Q: Can these bits be used with a standard hand drill or only a drill press?
A: These bits are compatible with any standard drill chuck — whether on a handheld power drill, a cordless drill, or a bench/floor drill press. For the most accurate threading and countersinking results, a drill press is recommended, but they work effectively with handheld drills as well.
Q: What metric thread sizes are included in the set?
A: The set covers the six most widely used metric thread sizes: M3, M4, M5, M6, M8, and M10 — giving you comprehensive coverage for the vast majority of metric fastener applications in one convenient kit.
