Description
Malco DT1CRP Replacement Blade Set for the DT1C 1" Cut-Off Duct Board Tool
The Malco DT1CRP is the factory replacement blade set for the Malco DT1C 1-inch cut-off duct board cutting tool. The set contains 3 blades, the full set the tool uses, so a worn DT1C cuts like new again after one quick swap.
In the DT1C, these blades make the straight edge cuts and shiplap joints used for end cuts and closing seams on 1-inch duct board. Sharp blades matter on duct board: a dull edge tears the fiberglass and the facing instead of slicing them, which leaves ragged seams that are harder to close and seal.
Key Features
Exact fit for the DT1C. Malco makes these blades only for the DT1C, so the cut depth and angle match the tool exactly.
Complete 3-blade set. Replaces every blade in the tool at once for an even, consistent cut.
Heat-treated stainless steel. Resists corrosion and holds a sharp edge through long runs of fiberglass board.
Keeps the tool in service. Swapping blades costs far less than replacing the DT1C, and the steel sled frame lasts for years.
Frequently Asked Questions
Which tool do these blades fit?
Only the Malco DT1C, the 1" cut-off duct board cutting tool. Malco makes a separate blade set for each size and cut type.
How many blades are in the set?
The DT1CRP contains 3 blades, which is the full set used in the DT1C.
When should I replace the blades?
Change them when the cut starts tearing the facing or fiberglass instead of slicing cleanly, or when the tool takes more force to push than it used to.
