Product Information
Full details
The JCB TurboJet HSS Drill Bit is an industrial-grade drilling solution designed for professionals and serious DIY enthusiasts who require precision and durability in metalwork and general drilling tasks. Its key benefit is the revolutionary TurboJet 7 cutting edge tip combined with M2 TiN lubrication, which delivers exceptionally fast and effortless penetration. While it offers superior wear resistance, users should note that as a high-hardness HSS bit, it is optimized specifically for precision and must be operated at correct speeds to avoid snapping under extreme lateral force.

FAQs
What materials is this drill bit suitable for?
This bit is optimized for drilling in metal and hard plastics.
Does the titanium coating wear off?
The TiN coating is a permanent ceramic layer designed for the life of the bit; it will eventually wear down with heavy usage, but it provides significantly extended life over uncoated bits.
Can this be used in a hammer drill?
It is not recommended. This bit is designed for rotational drilling; hammer action can damage the high-hardness HSS material.
What is the warranty period?
The JCB TurboJet HSS Drill Bit comes with a 3-year standard warranty.
What is the hardness rating?
The bit has a hardness rating of HRC 60-65.
Troubleshooting
Bit is getting very hot during use
Reduce your drilling speed (RPM) and ensure you are using appropriate cutting oil to assist with chip removal and cooling.
Drill bit is wandering or slipping
Use a center punch to create a small dimple before starting to guide the TurboJet tip, or verify that the bit is securely clamped in the chuck.
Pros and Cons
Pros
- Significantly longer lifespan compared to standard bits
- TurboJet 7 tip allows for faster drilling speeds
- TiN coating reduces heat build-up
- High hardness rating ensures edge retention
Cons
- Hardened steel can be brittle if used with lateral pressure
- Requires specific speed management for optimal results
- Limited to standard 12mm shank applications
Setup, Compatibility & Care
To ensure optimal performance, verify that your chuck can accommodate the 12mm diameter shank. Always use a center punch before starting your hole to aid the TurboJet tip. Proper care involves cleaning the bit of metal shavings after use and storing it in a dry, organized case to prevent oxidation. While the TiN coating is highly wear-resistant, avoid using high-impact or hammer settings, as the hardened HSS material is optimized for rotational cutting rather than percussion force. Occasionally applying cutting fluid can further extend the life of the bit during intensive drilling sessions.
