Product Description
CMT JT318VF-5 Jig Saw Blades - Wood and Metal Fine Straight Cut 5-Pc Pack delivers versatile cutting performance across a wide range of materials, from wood with embedded nails and chipboard to sheet metal and laminate. These bi-metal jig saw blades feature a progressive 10-15 TPI tooth configuration that transitions seamlessly between thin and thick workpieces, making them a reliable choice for contractors and woodworkers who need one blade to handle multiple material types in a single pass.
Key Features
- Bi-Metal (BIM) Construction - high-speed steel teeth bonded to a flexible spring-steel back deliver superior wear resistance and extended cutting life compared to single-material blades, meaning fewer blade changes and lower cost per cut.
- Progressive 10-15 TPI Tooth Pitch - the variable tooth spacing handles both thin and thick stock in one blade, reducing the need to swap blades when moving between sheet metal gauges and thicker wood panels.
- 1.7 mm Tooth Distance / Side-Set Geometry - precision tooth spacing produces fine, straight cuts in wood with nails, chipboard, laminate, and metal, minimizing tear-out and leaving cleaner edges that reduce finish sanding time.
- Universal T-Shank - fits all major corded and cordless jig saws without an adapter, so the blade is ready to install immediately on virtually any tool in the shop or on the job site.
- 4-Inch Cutting Height - accommodates material thicknesses from 1/8 in. up to 23/32 in. in metal and deeper cuts in wood, giving the user genuine flexibility across common structural and sheet goods dimensions.
- 5-1/2-Inch Total Blade Length - the extra length beyond the 4-in. cutting zone provides a stable stroke path and consistent tracking, helping maintain straight cut lines through dense or layered materials.
- 5-Piece Pack - multiple blades included in a single purchase ensures a ready supply for extended projects or job-site use, reducing downtime when a blade reaches the end of its service life.
Why This Product
- One blade for mixed-material work - the 10-15 TPI progressive pitch handles wood with embedded nails, chipboard, laminate, and sheet metal (1/8 in. to 23/32 in. thick) without stopping to change blades, which keeps workflow moving on renovation and demolition cuts.
- BIM construction resists the heat and friction generated when cutting through metal fasteners or aluminum profiles embedded in wood, extending blade life in the demanding conditions where standard HSS blades wear out quickly.
- The universal T-shank is compatible with all major jig saw brands, so there is no need to stock brand-specific blades - one part number covers the entire fleet of tools on a job site.
- Buying a 5-piece pack provides a cost-effective supply for high-volume or repetitive cutting tasks, ensuring a fresh blade is always available without a separate reorder before a project is complete.

Frequently Asked Questions
What does progressive TPI mean, and why does it matter for this blade?
Progressive TPI means the tooth pitch changes along the blade length - in this case from 10 TPI to 15 TPI. This variable spacing allows a single blade to cut efficiently through both thinner materials like sheet metal (where finer teeth prevent tooth stripping) and thicker stock like chipboard or wood with nails (where coarser teeth clear chips more aggressively). The result is one blade that performs across the full 1/8 in. to 23/32 in. thickness range without requiring a swap.
Will these T-shank blades fit my jig saw?
The T-shank (also called a universal T-shank) is the industry-standard shank type accepted by all major corded and cordless jig saw models. No adapter is needed. If your jig saw uses a T-shank quick-release chuck - which is the case for virtually all modern jig saws - these blades will install directly.
Can this blade cut through wood that contains nails or screws?
Yes. The JT318VF is specifically designed for straight cuts in wood with nails and embedded metal. The bi-metal construction - combining high-speed steel teeth with a flexible spring-steel body - resists the shock and heat generated when the blade contacts embedded fasteners, maintaining cutting performance where a standard carbon-steel blade would chip or break.
What is the actual usable cutting depth of these blades?
The cutting height is 4 in., meaning up to 4 in. of material can be engaged by the blade during a cut. The total blade length is 5-1/2 in., with the remaining length accommodating the T-shank and the stroke travel of the jig saw mechanism. For metal applications, the maximum material thickness range is 1/8 in. to 23/32 in. as specified for this blade.
