L.H. DOTTIE HPS138 Cup and Die Set
The L.H. DOTTIE HPS138 is a cup and die set designed for 1 inch conduit with a 1-3/8 inch sizing. It is intended for electricians and contractors who need to form precise conduit ends for threading or coupling in electrical installations.
Thermals, Noise and Power Draw in Normal Use
As a manual hand tool set, the HPS138 operates without a motor, electrical input or cooling system. It produces no operational noise, generates no heat and draws zero power during standard conduit preparation tasks.
Behaviour Under Sustained Load
The tool set relies entirely on user-applied force, so its performance under continuous use depends on the operator rather than mechanical limits. There are no thermal throttling concerns, duty-cycle restrictions or wear-related power drops during extended conduit forming sessions.

Questions about this item
How do I install the 1-3/8 inch cup and die set onto 1 inch conduit, and what step is commonly missed?
Align the cup squarely on the conduit end, then thread the die onto the pipe; the step often missed is applying cutting oil before turning the die to start clean threads.
What maintenance will the cup and die set need after repeated use on 1 inch conduit?
Clean metal shavings from the die teeth after each job, wipe both pieces with a light oil film, and store them dry to prevent corrosion on the cutting surfaces.
What limit appears first when using the 1-3/8 inch set continuously on 1 inch conduit?
The die teeth dull first under sustained threading, increasing torque required and producing rough threads; resharpening or replacement restores clean cuts.
