Bottom Slitter Knives

Bottom Slitter Knives

We are a Supplier of Bottom Slitter Knives in India manufactured keeping in view the requirement of the highly developing industrial world. The knives are sharp and highly durable. Bottom Slitter Knives are easy to install and can be widely used in several paper-cutting industries.

Bottom Slitter knives are harder than the top slitter knives preventing the usual burr from forming on the top blades during high-speed slitting. The bottom blade is just as important as the top slitter knives. Multi Groove Knives are available with a single or double cutting edge. We Offer these Bottom Slitter Knives in a wide range of specifications at affordable prices. The Sharp Cutting Edge combined with the precision mirror finish creates a dustless cut time after time. The bands are made from high-grade carbide steel to give higher performance.

Product FAQ's

1. How do Bottom Slitter Knives differ from top slitter knives?

Bottom Slitter Knives are mounted on the lower shaft to provide stability, accurate alignment, and consistent strip width control, while Top Slitter Knives are positioned above to rotate against them and perform the primary cutting action, ensuring clean slitting, smooth edges, and precise material separation during operation.

2. What are the standard sizes available for Bottom Slitter Knives?

DIC Tools works as a Bottom Slitter Knives manufacturer offering standard and custom diameters, thicknesses, and bore sizes based on specific machine requirements, with precision grinding ensuring high dimensional accuracy, while export orders support fully customized dimensions for diverse industrial applications.

3. What outer diameter range is available for Bottom Slitter Knives?

Bottom Slitter Knives are available with outer diameters ranging from 70 mm to 108 mm. This range supports different slitting machine configurations, board thickness requirements, and cutting loads, ensuring proper knife engagement, stable rotation, and consistent cutting accuracy across various industrial setups.

4. What is the standard cutting angle of Bottom Slitter Knives?

Bottom Slitter Knives are commonly manufactured with a standard cutting angle of 3 degrees. This optimized angle ensures smooth penetration into material, reduced cutting force, minimal fiber pull-out, improved edge quality, lower machine stress, and stable performance during continuous slitting operations.

5. Which materials are used to manufacture Bottom Slitter Knives?

Bottom Slitter Knives are manufactured using materials such as 9CrSi, SKD11 (D2), HSS, and other selected tool steels. These materials provide excellent wear resistance, edge stability, hardness uniformity, and long service life under heavy-duty slitting and converting applications.

6. How do Bottom Slitter Knives improve cutting quality?

Bottom Slitter Knives improve cutting quality by maintaining sharp, stable edges, precise concentricity, and optimized cutting angles. This combination reduces tearing, ensures straight cuts, minimizes material deformation, and delivers consistent slit widths across different corrugated board grades during continuous production.
