T-DRILL ND-54 Manual Tube End Notcher and Dimpling Tool, 12–54 mm Capacity

Condition: Used

Description

The T-DRILL ND-54 is a bench-mounted, manually operated tube-end preparation tool designed to notch and dimple branch tubing before it is inserted into a formed collar or tee outlet. The tool removes opposing crescent-shaped sections from the branch-tube end, helping create an open internal flow path after joining. During the same preparation process, it forms locating dimples that rest against the collar edge and act as insertion-depth stops.

This tool is a natural companion to the T-DRILL mechanically formed tee system. It is particularly useful when fabricating copper and other suitable malleable tubing assemblies for plumbing, HVAC, refrigeration, process piping, and industrial manifold production. The manual lever design requires no electrical or pneumatic supply.

Supported Tube Sizes

The indexed dial visible on this unit indicates the following nominal settings:

• 12 mm / 3/8 in
• 16 mm / 1/2 in
• 18 mm / 5/8 in
• 22 mm / 3/4 in
• 28 mm / 1 in
• 35 mm / 1-1/4 in
• 42 mm / 1-1/2 in
• 54 mm / 2 in

T-DRILL documentation for the related ND-54/PND-54 tooling family also lists a 14–16 mm range in some configurations. Confirm the installed jaw set and calibration before processing production tubing.

Features

• Manual operation eliminates the need for compressed air or electricity
• Indexed selector provides repeatable setup for multiple common tube diameters
• Combined notching and dimpling action reduces separate preparation steps
• Opposing crescent cuts help prevent the branch tube from obstructing the run-tube passage
• Formed dimples establish a repeatable insertion depth
• Heavy-duty metal base supports stationary workshop use
• Long handle provides mechanical leverage
• Compact footprint suits fabrication benches and maintenance shops
• Suitable for low-volume production, repair work, and field-preparation operations
• Designed to complement mechanically formed collar and tee-joint fabrication methods

Applications

• HVAC and refrigeration tube fabrication
• Copper plumbing assemblies
• Hydronic heating systems
• Heat-exchanger and coil manufacturing
• Industrial manifold production
• Process and utility piping
• Commercial refrigeration racks
• Boiler and mechanical-room piping
• OEM tubing fabrication
• Maintenance and repair workshops
• Prefabricated piping assemblies
• Tee-joint preparation before brazing, soldering, or other approved joining processes

Typical Operating Sequence

1. Rotate the indexed selector to match the outside diameter of the branch tube.
2. Insert the tube end into the appropriate jaw position.
3. Operate the long lever through its required stroke.
4. Remove the tube and inspect both relief notches and the locating dimples.
5. Insert the prepared branch into the correctly sized formed collar.
6. Complete the joint using the joining process specified for the tubing material and service.

The operator should verify tube diameter, wall thickness, material compatibility, jaw alignment, and insertion depth before beginning a production batch.

Advantages

• Performs two tube-preparation operations with one manual tool
• Produces more consistent branch ends than uncontrolled hand grinding
• Helps maintain an unobstructed flow opening at the tee intersection
• Requires no powered drive system
• Handles several common metric and nominal inch tube sizes
• Durable construction is appropriate for fabrication-shop environments
• Useful as a dedicated companion tool for collaring-machine installations

Limitations

• Intended for specific indexed tube diameters rather than unrestricted tube sizes
• Not a general-purpose hole saw or abrasive-style pipe notcher
• Tube-material and wall-thickness limits must be verified before use
• Worn or misaligned jaws can produce poor notch geometry
• The pictured unit shows significant cosmetic wear and should be cleaned, lubricated, inspected, and test-operated
• Accuracy should be verified with scrap tubing before production use
• Joining equipment and collar-forming machinery are not included

Compatible Systems and Assemblies

The ND-54 is designed for use within a mechanically formed tee-production workflow. It prepares the branch tube, while a separate collaring machine forms the outlet collar in the run tube.

Potential companion equipment includes:

• T-DRILL T-54 series portable collaring machines
• T-DRILL T-54c cordless collaring machines
• T-DRILL T-60 tee-forming machines
• T-DRILL S-54 production systems
• Other T-DRILL equipment capable of forming corresponding collars up to 54 mm

Compatibility depends on tube material, collar diameter, wall thickness, joining method, tooling configuration, and production standard. The T-54c family, for example, is used to produce formed tee outlets within the same general diameter range.

Cross-Referenced Models

Direct interchangeability should be confirmed before purchase.

• T-DRILL ND-54 — manual tube-end notcher
• T-DRILL PND-54 — powered or pneumatic tube-end notcher
• T-DRILL S-54 TBC — tube-end cutting and dimpling equipment associated with an S-54 system
• T-DRILL T-54 / T-54c — companion collar-forming machines rather than direct notcher replacements
• T-DRILL T-60 — related tee-forming machine used within a similar branch-fabrication process

Comparable Products

• T-DRILL PND-54 powered tube-end notcher
• Pneumatic branch-tube notching and dimpling machines
• Dedicated copper tube saddle-notch presses
• Rotary-hole-saw tube notchers with diameter-specific fixtures
• End-mill pipe notchers with adjustable tube vises
• Manual coping fixtures for copper and thin-wall tubing

Conventional abrasive, hole-saw, or end-mill notchers may create a saddle-shaped cut, but they generally do not reproduce the ND-54’s integrated locating-dimple function.

Inspection Recommendations

Before returning this unit to service:

• Clean debris and oxidation from the jaw area
• Inspect the selector dial and detents
• Check each jaw for cracks, chips, deformation, or missing hardware
• Verify that the lever pivots smoothly
• Inspect the base and mounting holes
• Check the center mechanism for excessive play
• Lubricate approved pivot and contact points
• Test every required setting with scrap tubing
• Confirm notch symmetry and dimple position
• Compare the prepared tube against the intended formed collar
