PRODUCT ADVANTAGES
Our customer service team is a dedicated, hard-working group specially selected for their enthusiasm and commitment to providing excellent customer service. They offer advice, answer any queries.
Laser Welded Safety:
Unlike standard sintered bits, our segments are laser-welded to the steel barrel. This prevents segment loss during high-heat dry drilling, making it safe for tough materials like reinforced concrete.
Turbo Segments:
Designed with "Turbo" or "Roof Top" segments to reduce friction, increase cutting speed, and clear dust efficiently from the hole.
Complete SDS Kit:
Comes ready to use with your rotary hammer. The set typically includes popular diameters (e.g., 38mm, 52mm, 65mm, 117mm, 127mm), an SDS Plus Adapter, a pilot drill for centering, and an extension bar for deep walls.
Built for Trades:
The perfect solution for electricians installing conduit, plumbers fitting waste pipes, and HVAC professionals installing vents through cavity walls.

1
Q1: Can I use this set with my drill on "Hammer" mode?
A: No! You must switch your SDS drill to Rotary Only mode. Using the hammer/impact action will shatter the diamond segments and void the warranty. The diamond grit grinds the material; it does not chip it like a masonry bit.
2
Q2: Will these bits cut through rebar?
A: Yes. The laser-welded segments are designed to cut through medium steel reinforcing bars (rebar) found in concrete. However, we recommend slowing down your drilling speed when you hit steel to prevent overheating.
3
Q3: Is this set for dry or wet drilling?
A: This is primarily a Dry Drilling Set, making it convenient for indoor work where water mess is not an option. The laser welding ensures the segments hold tight even without water cooling.
4
Q4: What sizes are included in the set?
A: (Customizable based on your stock, typically:) The set usually includes 38mm, 52mm, 65mm, 117mm, and 127mm bits, covering the most common pipe and vent sizes for UK/EU construction standards.
