Product Description
CMT JS644D-5 Reciprocating Saw Blades for Wood are 6-inch High-Carbon Steel (HCS) sabre saw blades engineered for fast, clean cutting through construction wood, wooden wall panels, particle board, and chipboard. Supplied in a 5-piece pack, these blades deliver a 4.3mm tooth distance and 6 TPI geometry that strikes a balance between cutting speed and surface quality - making them a reliable choice for framing, demolition prep, and panel work alike.
Key Features
- High-Carbon Steel (HCS) Construction - purpose-built for wood and wood-based materials, HCS delivers the toughness and edge retention needed for aggressive cuts through construction lumber, particle board, and chipboard without premature dulling.
- 6 TPI Tooth Configuration - six teeth per inch provides the ideal balance of cutting speed and surface quality in wood applications, reducing tearout while moving through material efficiently.
- 4.3mm Tooth Distance - consistent tooth spacing promotes chip evacuation and reduces binding in deep cuts, keeping the blade running freely through thick stock.
- 6-Inch Total Length with 5-Inch Cutting Height - the generous blade length handles construction members and wall panels with clearance to spare, allowing full strokes without bottoming out on the shoe.
- Cuts Material Up to 4 Inches Thick - rated for maximum workpiece thickness under 4 inches, these blades tackle dimensional lumber and built-up panels in a single pass.
- 0.049-Inch Blade Thickness - a slim kerf profile reduces material waste and allows the blade to track cleanly through straight and contoured cuts in wood panels.
- 5-Piece Pack - multiple blades included in a single purchase means you can keep spares on hand for continuous jobsite productivity without stopping to reorder mid-project.
Why This Product
- Designed specifically for wood cutting applications - including construction lumber, wooden wall panels, and engineered sheet goods like particle board and chipboard - these blades are matched to the materials most commonly encountered in framing and renovation work.
- The 6 TPI, 4.3mm tooth pitch geometry is optimized for wood sawing where both speed and cut quality matter, making these blades well suited for tasks ranging from rough framing cuts to panel trimming.
- At 6 inches long with a 5-inch cutting height, the blade reaches deep enough to handle thick construction members and layered wall assemblies in a single stroke - reducing repositioning and saving time on site.
- The 5-piece pack format keeps a ready supply of fresh blades available, so productivity is not interrupted when a blade reaches the end of its service life on a demanding cut.

Frequently Asked Questions
What materials are these reciprocating saw blades designed to cut?
These blades are designed for cutting construction wood, wooden wall panels, particle board, and chipboard. They are rated for material up to under 4 inches thick, making them suitable for a wide range of framing and renovation tasks involving solid wood and engineered wood products.
What is the difference between the total length and the cutting height on these blades?
The total blade length is 6 inches, which includes the shank and the full blade body. The cutting height - the usable portion of the blade that actually engages the material - is 5 inches. The 19mm cutting depth specification further defines the effective reach into the workpiece during a cut.
Why is High-Carbon Steel (HCS) used for these wood-cutting blades?
High-Carbon Steel is the preferred material for reciprocating saw blades intended for wood and wood-based applications. HCS provides sufficient hardness and toughness to maintain a sharp cutting edge through construction lumber, particle board, and chipboard, and it performs well in the cutting speeds typical of sabre saw use on these materials.
How many blades are included in the JS644D-5 pack, and why does that matter on a jobsite?
The JS644D-5 is supplied as a 5-piece pack. Having multiple blades on hand means you can swap to a fresh blade immediately when one dulls during demanding cuts through thick construction wood or engineered panels, keeping work moving without downtime to source replacement blades.
