Super Tool 4″ HSS Slitting Saw 36 Teeth 1/8″ Width 1″ Arbor

Description

Product Overview

The Super Tool 4‑inch high speed steel (HSS) slitting saw is a precision‑engineered cutting accessory designed for demanding industrial and scientific applications. Constructed from premium HSS material, the saw offers exceptional hardness, wear resistance, and the ability to maintain a sharp cutting edge even under high temperature conditions. The tool features a straight‑tooth geometry with 36 meticulously ground teeth that provide consistent chip removal and reduce vibration during operation. With a tool diameter of 4 inches, a face width of 1/8 inch, and a 1‑inch arbor hole, the saw delivers a balanced profile that fits standard milling machines and arbor‑type cutters without the need for additional adapters. The tight tolerance on the tool diameter (+0.0625″/‑0″) and the arbor hole (+0.001″/‑0″) ensures a secure fit, minimizing run‑out and delivering repeatable accuracy across multiple workpieces. The compact size and lightweight design, weighing only 6.24 ounces, make it easy to handle, store, and integrate into a wide range of machining setups, from small bench‑top mills to larger production‑grade equipment.

Technical specifications include a product dimension of 4 × 0.12 × 4 inches, a weight of 6.24 oz, and a model number 140335. The saw complies with industry standards for arbor‑type milling cutters and is classified under side & face milling cutters, reflecting its suitability for both side‑cutting and face‑cutting operations. The high‑precision manufacturing process guarantees that each tooth is positioned with exact spacing, delivering uniform material removal and extending tool life. The HSS alloy composition is optimized for high tensile strength and resistance to deformation, making the saw capable of handling high‑speed spindle rotations without loss of dimensional stability.

Usage

This slitting saw excels in a variety of material removal tasks where clean, narrow slots are required. It is ideally suited for cutting thin sheets of carbon steel, stainless steel, aluminum, brass, and even engineering plastics such as acrylic and polycarbonate. The straight‑tooth design produces a smooth, burr‑free finish, reducing the need for secondary deburring operations. Typical applications include creating keyways, slots for fastening hardware, precision openings for ventilation or wiring channels, and trimming excess material from fabricated components. The saw can be employed in both manual and CNC‑controlled milling environments, making it a versatile choice for prototype development, small‑batch production, and high‑volume manufacturing.

Operators benefit from the tool’s predictable feed rates and low cutting forces, which help extend tool life and improve overall machining efficiency. Proper coolant application—preferably a high‑pressure mist or flood system—significantly reduces heat buildup, especially when cutting harder alloys. Recommended spindle speeds range from 3,000 to 5,000 RPM for steel, with feed rates adjusted to 0.001–0.003 in per tooth for optimal chip evacuation. For softer materials such as aluminum or plastics, higher speeds and slightly increased feed can be used, always maintaining a stable chip load to avoid tooth chatter. Safety considerations include securing the workpiece firmly, using appropriate eye protection, and ensuring the arbor is correctly seated to prevent tool wobble.

In addition to standard milling machines, the saw is compatible with vertical machining centers (VMCs) and horizontal machining centers (HMCs) that accept a 1‑inch arbor. Its compact geometry allows for tight clearance operations, enabling users to machine intricate features in confined spaces. When integrated into automated CNC programs, the saw’s consistent tooth geometry ensures repeatable results across thousands of cycles, making it a cost‑effective solution for high‑throughput production lines.

FAQ

What materials can this slitting saw cut effectively?

The saw is designed to handle a broad range of metals, including carbon steel, stainless steel, aluminum, brass, and copper alloys, as well as non‑metallic materials such as acrylic, polycarbonate, and other engineering plastics.

What spindle speed and feed rate are recommended?

For most steel applications, a spindle speed between 3,000 and 5,000 RPM combined with a moderate feed rate of 0.001 to 0.003 inches per tooth yields clean cuts. Adjust speeds lower for harder alloys and higher for softer materials, always using appropriate coolant.

Can this saw be used on CNC machines?

Yes, the 1‑inch arbor hole conforms to standard CNC milling machine specifications, allowing seamless integration into automated machining programs. Ensure the tool holder matches the arbor size and verify tool path clearance before operation.

How do I maintain the cutting edge for optimal performance?

Regularly inspect the teeth for wear or chipping. If dullness occurs, use a fine‑grit sharpening stone or send the saw to a qualified sharpening service. Maintaining proper coolant flow and avoiding excessive feed rates also help preserve edge integrity.

Is there a warranty or guarantee for this product?

Super Tool provides a limited one‑year warranty covering manufacturing defects and offers a satisfaction guarantee that includes replacement or repair of any tool that fails to meet performance expectations under normal operating conditions.
