Product Information
Full details
This 170-piece drill bit set is an ideal choice for professional tradespeople and industrial users who require a wide range of precision tools for drilling through steel, wood, plastics, and non-ferrous metals. The primary benefit is the Titanium Nitride (TiN) coating, which significantly extends the service life of each bit compared to standard high-speed steel alternatives; however, users should note that the large size of the set requires dedicated storage space in a workshop environment.

FAQs
Are these bits compatible with standard power drills?
Yes, these are designed to be used with standard drill chucks found on most professional power drills and drill presses.
Can these be used on concrete or masonry?
No, these are high-speed steel (HSS) bits with a TiN coating designed for metal, wood, and plastic; they are not intended for concrete or masonry.
How do I sharpen these bits?
While the TiN coating is durable, you can sharpen them using a standard grinding wheel, though note that sharpening will remove the titanium coating at the cutting edge.
Is the case lockable?
The case features secure snap fasteners to keep it shut during transport, but it does not include a keyed lock mechanism.
What is the benefit of a 118-degree split point?
A 118-degree split point reduces the force required to start the hole and prevents the bit from 'walking' across the surface of the material.
Troubleshooting
Bit is slipping in the drill chuck
Ensure the drill chuck is fully tightened and the bit shank is free of oil or debris before insertion.
Excessive heat while drilling
Apply a cutting fluid or lubricant to the drill point and reduce the drill speed to prevent premature dulling of the bit.
Bit wandering when starting a hole
Use a center punch to create a small dimple at the drilling location before starting, or ensure the split point is properly centered.

Setup, Compatibility & Care
To ensure the longevity of your drill bit set, store the bits in their designated slots within the metal case when not in use. Ensure that the drill press or hand drill chuck is tightened securely before operation to prevent slippage. When working with harder metals, use a quality cutting oil to reduce friction and heat, which preserves the integrity of the titanium coating. Regularly wipe down the bits with a dry cloth to remove metal shavings and grit before placing them back into the case. Avoid exposing the case to excessive moisture to prevent surface oxidation on the metal finish.
