Professional-grade hex shank step drill bits specifically designed for PPR pipe end preparation and repair work. These innovative three-stage step drill bits allow plumbers and electricians to perform pipe end counterboring, chamfering, and cleaning in a single operation. The unique 20mm/25mm/32mm stepped design matches standard PPR pipe sizes, creating perfect recesses for fittings and removing damaged pipe sections. With quick-change 1/4" hex shank compatibility, these bits work with most drills and impact drivers, making them essential for efficient plumbing installations and maintenance.
- Three-Stage Design: Single-bit handles 20mm, 25mm, and 32mm PPR pipe sizes
- Quick-Change Hex Shank: 1/4" hex shank for fast bit changes in drill drivers
- Pipe End Preparation: Combines counterboring, chamfering, and cleaning functions
- PPR-Optimized Geometry: Special cutting angles prevent material tearing and ensure clean finishes
- Through-Tool Cooling: Internal coolant channels for extended bit life (on compatible models)

Frequently Asked Questions
What pipe materials can these drill bits be used on?
These step drill bits are specifically optimized for PPR (Polypropylene Random Copolymer) pipes and multi-layer plastic pipes commonly used in plumbing and electrical conduit setups.
What pipe dimensions are supported by the three-stage design?
The drill bits feature steps matching standard pipe sizes of 20mm, 25mm, and 32mm, which correspond to standard DN20, DN25, and DN32 plumbing installations.
Are these bits compatible with standard drills and impact drivers?
Yes, they are designed with a quick-change 1/4" hex shank, ensuring universal compatibility with most standard power drills, drill drivers, and impact drivers.
What are the benefits of the titanium coating on the high-speed steel?
The Titanium coating reduces friction, decreases heat buildup during operation, and significantly extends the lifespan of the High-Speed Steel (HSS) material.
Can these tools be used for repairing damaged plumbing pipes?
Absolutely. They are highly effective at cleaning and preparing pipe ends, removing damaged sections, and creating precise recesses for leak-proof repair couplings.
