Also, customized service and OEM&ODM service are available.
The 6KTD8-1 is a factory replacement cutter knife for the KT2 series tobacco leaf cutting machine, catalogued as part number 15KTF10. It is manufactured from alloy tool steel heat-treated to HRC62 and finish-ground on a dedicated CNC grinding center to a dimensional tolerance of ±0.005mm, ensuring consistent blade thickness and a flat, burr-free seating surface that fits the KT2 holder without shimming or adjustment.
Products Description
The 6KTD8-1 cutter knife meets the dimensional and hardness requirements of the KT2 tobacco cutting machine. Key manufacturing controls:
Material & hardness
Alloy tool steel, vacuum heat-treated and oil-quenched to HRC62 – maintains a sharp edge under high-frequency cutting without chipping.
Thickness precision
CNC finish-ground to ±0.005mm. Consistent thickness ensures proper seating in the KT2 holder, preventing uneven clamping and edge wear.
Profile accuracy
Seibu Wire EDM M50B cuts outline and slots to ±0.01mm, guaranteeing drop-in fit without adjustment.
Surface finish
Ra ≤0.4μm ultra-precision ground finish reduces tobacco adhesion and keeps the cut edge clean during long runs.
Corrosion resistance
Moderate for organic acids/moisture; stainless steel or PVD-coated variants available for high-humidity or high-moisture burley blends.
Quick-change design
Matches KT2 OEM mounting – no custom tooling required for installation or removal.

All standard alloy tool steel blades are finish-ground in-house on our CNC precision grinding equipment to a thickness tolerance of ±0.005mm and profiled on a Seibu Wire EDM M50B. For cemented carbide variants, we use specialized carbide grinding wheels to maintain the same dimensional control.
FAQ
Q: Is the 6KTD8-1 knife a direct OEM-equivalent replacement for the KT2 machine?
A: Yes. The 6KTD8-1 is dimensioned to the KT2 OEM blade specification. Profile geometry is cut on a Seibu Wire EDM to ±0.01mm, and blade thickness is ground to ±0.005mm, so it seats correctly in the original holder without modification.
Q: What level of dimensional variation should I expect between blades in the same batch?
A: For standard alloy tool steel blades, our CNC precision grinding process holds thickness variation within ±0.005mm across a production batch.
Q: Can Hansheng produce blades to a non-standard size?
A: Yes. Send us your dimensional drawing or a physical sample and we will produce to those specifications.
Q: What is the expected service life under normal production conditions?
A: Under single-shift operation with standard mixed-leaf tobacco at normal moisture content, alloy tool steel blades typically require resharpening after 3 to 6 months. Three-shift continuous production or high-stem-content blends will shorten this interval. Cemented carbide blades manufactured to the same 6KTD8-1 profile typically deliver 3 to 5 times the service interval of tool steel under equivalent loads.
Q: How are blades packed for export shipment?
A: Each blade is wrapped in VCI anti-rust film to prevent oxidation during sea transit, then packed in rigid foam-lined cartons. Export-standard packaging for both air and sea freight is available.
Q: Is there a minimum order quantity?
A: Custom materials or non-standard dimensions typically require a minimum of 5 pieces. Contact us for quantity-based pricing.
