13-Pc HSS Titanium Twist Drill Bit Set 1.5–6.5mm | Metal & PVC

13-Piece HSS Titanium-Coated Twist Drill Bit Set — 1.5mm to 6.5mm

Tackle any drilling project with confidence using this 13-piece High Speed Steel (HSS) twist drill bit set. Each bit is precision-ground with a titanium coating that dramatically extends cutting life, reduces heat buildup, and keeps edges sharper for longer. Whether you're drilling through sheet metal, aluminium, PVC board, wood, or plastic, this versatile kit has the right size ready to go.

Key Features

• Complete 13-Piece Set: Sizes range from 1.5mm to 6.5mm in 0.5mm increments — covers the most common everyday drilling sizes in one convenient kit.
• Titanium Coating (TiN): Gold-coloured titanium nitride coating increases surface hardness, lowers friction, and extends bit service life compared to uncoated HSS bits.
• High Speed Steel Construction: HSS material withstands high-temperature drilling without losing its temper, making it suitable for both metal and non-metal materials.
• Round Shank Design: Standard round shanks fit securely in all keyless and keyed drill chucks — no adapters needed.
• Precise 118° Tip Angle: The split-point tip geometry helps the bit self-centre on contact, reducing walking and delivering clean, accurate holes.
• Wide Material Compatibility: Designed for metal, aluminium, copper, PVC board, wood, and general plastics.
• Organised Storage Case: Bits are stored in a clearly labelled index case so you can grab the right size at a glance and keep your workshop tidy.

What Can You Drill?

These bits are optimised for:

• Mild steel, stainless steel, aluminium, and copper sheet
• PVC board and general plastics
• Softwood and hardwood
• DIY home improvement, electrical work, and workshop fabrication tasks

Pro Tips for Best Results

• Use a centre punch to mark your drilling spot before starting — this helps the bit stay on target.
• Apply light cutting oil when drilling through metal to reduce heat and prolong bit life.
• Start at a lower speed and increase gradually for larger diameter bits.
• Clear metal swarf regularly to prevent clogging the flutes.

Frequently Asked Questions

Q: What materials can these HSS titanium twist drill bits cut through?

A: These 13-piece HSS titanium-coated twist drill bits are designed for drilling through mild steel, aluminium, copper, PVC board, general plastics, and softwood or hardwood. The titanium nitride coating helps maintain sharpness when working with harder materials like metal sheets.

Q: What drill chuck size is compatible with this set?

A: The drill bits feature a standard round shank that fits any drill with a standard keyless or keyed chuck — typically 10mm or 13mm chucks used on most home and professional cordless or corded drills and drill presses. No adapters are required.

Q: How do I maintain the titanium-coated drill bits to get the longest life?

A: To extend the service life of your titanium twist drill bits, apply a few drops of cutting oil when drilling metal, avoid excessive downward pressure (let the bit do the work), clear flutes of swarf regularly, and store bits in the provided index case to prevent edge damage between uses.

Q: Is the titanium coating the same as a solid titanium drill bit?

A: No — these are High Speed Steel bits with a titanium nitride (TiN) surface coating. The TiN coating increases surface hardness and reduces friction, significantly improving performance and durability over standard uncoated HSS bits, but the core material is HSS. Solid titanium bits are rare and unnecessary for typical drilling applications.
