Product Information
Full details
The Minotaur HSS Titanium Drill Bit 3-pack is designed for metalworkers, woodworkers, and DIY enthusiasts who require high-precision hole drilling in dense materials. These bits provide the key benefit of extreme durability and reduced friction thanks to their titanium nitride coating, though their small 1.5mm diameter makes them susceptible to snapping if handled with excessive lateral force.

FAQs
Can I use these bits in an impact driver?
While they will fit the chuck, impact drivers are generally too aggressive for 1.5mm bits; a standard drill driver is highly recommended.
Do I need a center punch with these bits?
No, the 118-degree split point is designed to prevent walking, making a center punch optional for most surfaces.
Can these be sharpened?
Due to their small 1.5mm size and the specific titanium coating, they are difficult to sharpen effectively; it is recommended to replace them when blunt.
What is the maximum depth I can drill?
The bits are 40mm in length, but they are best used for drilling depths up to 25-30mm to ensure proper chip clearance.
Are these suitable for hardened steel?
They are designed for standard metals and non-ferrous materials; they may wear down quickly if used on hardened or tool-grade steels.
Troubleshooting
Bit slipping on the material surface
Ensure you are using the split-point tip correctly and applying enough initial pressure to engage the metal surface.
Bit snapping during use
Check your drill angle. Lateral pressure or a wobbling drill chuck is the primary cause of breakage for 1.5mm bits.
Overheating/discoloring of the bit
Apply cutting fluid and reduce the feed pressure to allow the bit to clear material more efficiently.
Pros and Cons
Pros
- Precision 118-degree split point prevents slipping
- Titanium coating reduces friction and heat damage
- High-quality M2 steel construction for longevity
- Excellent for pilot holes and high-accuracy work
Cons
- Small 1.5mm size requires a steady hand to avoid snapping
- Not suitable for heavy-duty impact drilling
- Limited to smaller fastener applications
Setup, Compatibility & Care
These bits are compatible with all standard 3-jaw chuck drill drivers. To ensure longevity, follow these best practices:
- Setup: Secure your workpiece with clamps to prevent movement; because the bits are thin (1.5mm), any vibration can lead to breakage.
- Lubrication: When drilling into ferrous metals like steel, use cutting oil to further reduce friction and improve the surface finish of the hole.
- Speed Control: Use the correct drill speed setting; small bits generally require higher RPMs but low, controlled feed pressure.
- Storage: Store the bits in a dry, organized case to prevent contact with other metal tools, which can chip the hardened cutting edges.
