Product Description
CMT JT127D-5 Jig Saw Blades - Aluminum/Fine Straight (HSS) 4" x 8 TPI - 5-Piece Pack by CMT delivers precision straight cuts through aluminum sheet, thin-wall pipes, profiles, plastics, and fiberglass. Built from High-Speed Steel (HSS) and engineered with a fine 8 TPI tooth pattern, these jig saw blades are purpose-designed to handle aluminum ranging from 1/8 in. to 5/8 in. thick as well as pipes and profiles with a diameter under 1-1/4 in. Whether you are cutting aluminum channel, thin sheet metal, or fiberglass panels, the optimized tooth geometry keeps chips clear and cuts straight. This listing includes 5 blades per pack, making it an efficient choice for production work and trade professionals who need a ready supply of quality metal-cutting blades on hand.
Key Features
- HSS (High-Speed Steel) Blade Material - High-Speed Steel construction stands up to the demands of cutting non-ferrous metals, allowing clean cuts through aluminum, plastics, and fiberglass without premature tooth wear.
- Fine 8 TPI Tooth Configuration - Eight teeth per inch delivers a fine, controlled cut that minimizes burring on aluminum sheet and thin-wall profiles, reducing the need for secondary finishing work.
- 3 mm Tooth Distance (JT127D Profile) - The 3 mm tooth spacing is matched to aluminum and non-ferrous metals, preventing chip packing in the gullets during cutting so the blade stays efficient and cuts straight.
- Universal T-Shank - The T-shank interface fits all major jig saws and cordless jig saws - no adapter or special tooling required, making blade swaps fast and reliable on the job site or in the shop.
- 4 in. Total Length with 3 in. Cutting Height - The 4 in. blade length and 3 in. usable cutting depth give you reach for aluminum stock and profiles while keeping the blade rigid enough for straight, accurate cuts.
- Optimized for Aluminum Thin to Thick (1/8 in. to 5/8 in.) - The blade geometry is specifically developed for the 1/8 in. to 5/8 in. material range, meaning it performs consistently across a variety of aluminum sheet gauges without needing to switch blades.
- Suitable for Pipes and Profiles Under 1-1/4 in. Diameter - Rated for cutting pipes and profiles with a diameter under 1-1/4 in., making this blade useful for plumbing-adjacent metalwork and structural profile trimming in aluminum or plastic extrusions.
- 5-Piece Pack - Five blades per pack keeps production moving and reduces downtime from blade changes, particularly valuable for shops or contractors cutting aluminum and non-ferrous materials on a regular basis.
Why This Product
- The JT127D tooth geometry is purpose-built for aluminum rather than adapted from a general-purpose blade - the 3 mm tooth spacing and 8 TPI count are selected specifically for non-ferrous metals, thin-wall pipes, and plastic extrusions, resulting in a cleaner straight cut with less chatter.
- With a rated cutting range of 1/8 in. to 5/8 in. thick aluminum plus compatibility with pipes and profiles up to 1-1/4 in. diameter, one blade type covers the majority of aluminum sheet and profile work without requiring multiple blade SKUs.
- HSS construction gives these blades durability in metal-cutting applications where standard bi-metal alternatives may be overkill for thin aluminum - keeping cost per cut competitive for high-volume use.
- The universal T-shank design means these blades drop straight into virtually any professional or cordless jig saw in the shop, eliminating compatibility concerns and making the 5-piece pack immediately usable across different tools on a crew.

Frequently Asked Questions
What materials can the CMT JT127D-5 blades cut?
These blades are specifically designed for aluminum (1/8 in. to 5/8 in. thick), pipes and profiles with a diameter under 1-1/4 in., plastic, and fiberglass. The 8 TPI fine tooth pattern and 3 mm tooth spacing are optimized for non-ferrous metals and similar materials - they are not intended for wood or general-purpose cutting.
What jig saw shank type do these blades use, and will they fit my saw?
These blades use a T-shank (universal T-shank) interface. The T-shank is the industry-standard fitting accepted by virtually all major corded jig saws and cordless jig saws currently on the market. No adapter is required.
How thick of aluminum can the JT127D blade cut?
The blade is rated for aluminum from 1/8 in. up to 5/8 in. thick. For pipes and profiles, it is rated for diameters under 1-1/4 in. The 3 in. cutting height accommodates stock within this range.
How many blades are included in the JT127D-5 pack?
This listing is for the JT127D-5 five-piece pack. You receive 5 individual HSS jig saw blades, each 4 in. in total length with a T-shank, in a single package.
