Product Information
Full details
The Minotaur HSS Titanium Drill Bit is designed for metalworkers, woodworkers, and DIY enthusiasts who require precision and durability when drilling through challenging materials like steel, aluminium, and hardwood. Its titanium coating provides superior heat management and longevity, allowing for smooth, effortless hole creation. While these bits offer high performance, users should note that they are specifically optimized for standard drilling tasks and may require careful speed control when used on extremely hardened alloys.

FAQs
Can I use these bits for masonry or concrete?
No, these are HSS Titanium bits intended for metal, wood, and plastic. Using them on masonry will dull the cutting edge immediately.
Do I need a center punch with these bits?
The 118-degree split point is designed to start on contact, but a center punch can still be used for high-precision layout work.
Are these bits compatible with standard drill chucks?
Yes, they fit standard drill drivers, including both cordless and corded models.
How do I know when the bit is dull?
If you find yourself needing to apply excessive downward pressure to make the bit cut, it is a sign that the cutting edge is no longer sharp.
Can these bits be used in a drill press?
Yes, they perform exceptionally well in a drill press due to their fully ground construction and precision geometry.
Troubleshooting
The drill bit is sliding off the mark.
Ensure the drill is perpendicular to the surface. If the surface is exceptionally smooth, consider using a center punch to create a tiny indentation for the tip to sit in.
Bit is getting very hot and smoking.
The drill speed is likely too high for the material. Decrease the RPM and apply a cutting fluid to help dissipate the heat.
The hole is not clean or has rough edges.
Check if the bit has become dull from heavy use. If the cutting edge appears rounded, it may need to be replaced.
Pros and Cons
Pros
- Excellent heat dissipation due to titanium coating
- Split point design eliminates the need for center punching
- Highly durable against shearing under heavy loads
- Versatile application across wood, metal, and plastic
- Smooth finish on holes reduces the need for secondary filing
Cons
- Not suitable for extremely hardened steel or masonry
- Titanium coating will wear away over time with heavy use
- Requires proper speed adjustment to avoid overheating the tip
Setup, Compatibility & Care
These bits feature a standard shank compatible with most corded and cordless drill drivers using a keyless or keyed chuck. To ensure a secure grip, always tighten the chuck jaws firmly around the shank.
Care Instructions
- Speed Control: Run the drill at lower speeds for metal to prevent heat buildup.
- Lubrication: Use cutting oil when drilling into steel or aluminium to extend the life of the edge.
- Cleaning: Wipe the bit clean of metal shavings and wood dust after each use.
- Storage: Store in a dry environment to prevent oxidation on the un-coated areas of the shank.
