Prevost Drill For Tapping Flange

Prevost Drilling Tool for Tapping Flanges

The Prevost Drilling Tool is a specialized hole-cutting instrument engineered specifically for installing Prevost “Quick Drop” Tapping Flanges. Unlike standard twist drills or generic hole saws, this tool is designed to cut a precise, clean hole in the aluminum pipe wall while guaranteeing the safety of the system.

Its critical function is to prevent debris contamination. The drill is constructed to retain the “coupon” (the circular disk of aluminum cut from the pipe), ensuring it is pulled outward rather than falling inside the pipe where it could cause blockages or damage downstream equipment.

Key Features & Benefits

• “Coupon” Retention Safety: The most important feature of this tool is its ability to capture the cut piece of aluminum (the slug) inside the bit or on the pilot. This prevents the metal disk from dropping into the main air stream, which is a major hazard with standard hole saws.
• Precision Sizing: Manufactured to the exact diameter required for Prevost Tapping Flanges (PPS1 BP). This ensures the hole perfectly matches the flange’s O-ring seal, guaranteeing a leak-free fit.
• Pilot Drill Stability: Features a central pilot bit that centers the tool on the pipe surface, preventing “walking” or slipping during the start of the cut, which could scratch the pipe exterior.
• Clean Cutting Action: Sharp, hardened cutting teeth slice through the aluminum smoothly, minimizing the creation of fine metal shavings or swarf entering the pipe.
• Depth Control: When used in conjunction with the Prevost Drilling Jig, the tool cannot drill too deep, preventing accidental damage to the opposite wall of the pipe.

Technical Specifications

• Part Series: PPS1 PE (Drill / Hole Saw)
• Type: Hole Saw with Pilot Bit & Slug Retention Spring/Wire
• Material: Bi-Metal or Hardened High-Speed Steel (HSS)
• Shank: Standard hex or round shank (fits standard power drill chucks)
• Cut Diameter: Matched to specific flange sizes (e.g., 16mm, 22mm holes, etc.)
• Compatibility: Must be used with the corresponding size of Tapping Flange.

Ideal Applications

• Safe Retrofitting: The only approved method for cutting holes in an installed Prevost header to add a new drop.
• Live System Modification: (When used with proper isolation/safety procedures) allows for adding drops without dismantling the entire pipe run.
• Vertical & Overhead Drilling: The retention feature makes it safe to drill into overhead pipes without the slug falling down the vertical section.

Prevost PPS DRIL – Under-Pressure Drilling Tool

Expand Your Air System Without the Downtime

The Prevost PPS DRIL is a specialized engineering solution designed for the Prevost Piping System (PPS). It allows for the installation of new air drops or branch lines on an existing aluminum pipe network while the system is fully pressurized.

Traditionally, adding a new outlet required shutting down the compressor, venting the entire system, drilling the pipe, and cleaning out metal shavings—a process that halts production. The PPS DRIL eliminates this entire bottleneck, allowing for “live” system expansion in minutes.

Key Features

• Zero-Downtime Installation: Add a new drop or branch line without turning off the air supply. This is a game-changer for 24/7 manufacturing facilities where every minute of downtime is a lost expense.
• Chip-Free Operation: The tool is designed to contain and evacuate the aluminum shavings produced during the drilling process. This prevents metal chips from entering the air stream and damaging downstream tools, valves, or cylinders.
• Precision Alignment: Specifically engineered to work with PPS “Branc” (Branching) clamps. The tool guides the drill bit perfectly into the center of the pipe, ensuring a clean, leak-free seat for the new fitting.
• Universal PPS Compatibility: Designed to work across the various diameters of the PPS aluminum pipe range. It provides a standardized, repeatable drilling depth and diameter every time.
• Safe and Controlled: The tool manages the pressure release during the “breakthrough” phase of drilling, ensuring the operator is protected from sudden air discharge or tool kickback.

How It Works: The “Hot Tap” Process

1. Mount the Clamp: Secure a PPS branching clamp (saddle) onto the pipe at the desired location.
2. Attach the PPS DRIL: Mount the drilling tool directly onto the valve or outlet of the branching clamp.
3. Drill Live: Use a standard power drill to drive the PPS DRIL bit through the pipe wall. The tool maintains a seal throughout the process.
4. Extract & Seal: Withdraw the drill bit, close the branch valve, and remove the tool. You now have a live, clean air port ready for a new drop.

The Professional Advantage

The PPS DRIL transforms air system maintenance from a major weekend project into a simple task that can be performed during active work hours. It is the essential tool for growing businesses that need to move workstations or add machinery without affecting the rest of the facility’s operations.

Ideal Applications

• Expanding Assembly Lines: Adding new drops for pneumatic tools as production needs grow.
• Retrofitting CNC Machines: Providing air supply to new equipment without stopping existing machines.
• Modular Workspaces: Quickly reconfiguring shop layouts in automotive or aerospace hangers.
• Emergency Additions: Installing an air point for a new repair station or safety equipment on short notice.
