Replacement saw blade 300 mm 14 TPI Kirschen 4301300

A replacement saw blade 300 mm long with 14 teeth per inch, made in Japan for the Kirschen carpentry saw No. 4400300. The blade restores cutting performance on an extra-long carpentry saw without buying a new tool. Tooth pitch of 14 TPI moves quickly through softwood and hardwood alike. The working length covers beams and purlins up to 300 mm wide.

Carpenters use this blade for rough cuts during timber framing, roof structure work and general site joinery. Stated hardness is 61 HRC, which supports edge retention over long cutting sessions. The blade mounts on the original saw frame, so handle and grip stay unchanged. Keeping a spare blade in the shop shortens downtime when the cutting edge dulls. It fits professional joinery shops, furniture workshops and construction sites where large sections are cut by hand.

Replacement saw blade 300 mm for Kirschen carpentry saws

The blade belongs to the Kirschen carpentry saw system and pairs with saw No. 4400300. Length and tooth count are matched to rough dimensioning work rather than fine joinery. Japanese manufacture defines the tooth grinding and the steel treatment. The result is a blade that bites fast and keeps a usable edge under repeated site use.

Blade construction and key figures

Steel hardness at 61 HRC keeps the teeth sharp during continuous cutting of dry timber. The 300 mm blade length gives a long, stable stroke, which reduces the number of passes on wide beams. The mounting matches the original carpentry saw, so replacement takes only the standard blade change procedure described for that saw.

• Blade length: 300 mm
• Tooth pitch: 14 teeth per inch
• Stated hardness: 61 HRC
• Compatible saw: Kirschen carpentry saw No. 4400300
• Maximum beam width handled: 300 mm
• Function: replacement blade for an extra-long carpentry saw

Because the tooth pitch is fixed at 14 TPI, the cut is fast and slightly coarse. That trade-off suits rough cutting before planing or final machining. Users who need a finer surface should plan a finishing operation afterwards. The blade works on both softwood and hardwood sections within the stated width limit.

Cutting behaviour in practice

Tooth geometry lowers the push force needed on each stroke. Less effort per stroke means faster progress on long cuts and less hand fatigue during repetitive work. On wide beams, the full 300 mm length lets the operator use the whole blade instead of short, choppy strokes. Edge wear stays predictable when the blade is kept clean and dry.

• Suited to rough cuts and fast dimensioning
• Handles purlins, beams and heavy timber bars
• Long stroke reduces the number of passes
• Sharpness maintained through continuous workshop use

Store the blade protected from moisture to avoid corrosion on the teeth. Check tooth set before demanding cuts. If the kerf starts to wander or the cut slows noticeably, fit a fresh blade rather than forcing the stroke.

Common applications

Joinery shops and furniture workshops use the blade for initial breakdown of rough stock. On construction sites it serves timber frame assembly, roof truss work and purlin cutting. Carpenters reach for it when a beam has to be shortened on the spot. It also covers quick trimming of large bars before fine machining. The 300 mm width limit defines the practical range of sections.
