SGIH 26-5 Slot Grip Cut-Off Blade for GTN Carbide Inserts – Dorian

Description

Product Overview

The SGIH 26-5 slot grip cut off blade is a precision‑engineered cutting component designed specifically for use with GTN carbide indexable inserts. Constructed from high‑grade alloy steel that has been heat‑treated to a hardness of 62 HRC, the blade offers a balance of toughness and wear resistance that enables clean, burr‑free cuts on a wide range of ferrous materials. The slot‑grip geometry provides a secure clamping interface that eliminates slippage during high‑speed machining, while the 26‑5 designation indicates a 26 mm overall length with a 5 mm slot width, delivering a compact footprint that fits tightly into standard tool holders. The blade’s cutting edge is ground to a fine 0.5 mm radius, reducing cutting forces and extending insert life. This combination of material quality, dimensional precision, and ergonomic design makes the SGIH 26‑5 an ideal choice for demanding production environments where consistency and reliability are paramount.

The blade is forged from a single billet of alloy steel, then undergoes CNC machining to achieve exact tolerances on the slot dimensions and edge profile. After machining, each piece is subjected to a controlled quench and temper cycle that eliminates internal stresses and maximizes hardness uniformity. A final surface‑finish polishing step removes microscopic imperfections that could otherwise initiate micro‑cracks during operation. Dorian Tool’s in‑house quality assurance team inspects every blade with a calibrated coordinate‑measuring machine (CMM) to verify that the slot width, length, and edge radius fall within the specified ±0.02 mm tolerance band. Only blades that pass this rigorous inspection are released for packaging, ensuring that every customer receives a product that meets the exacting standards required for high‑performance cutting.

The SGIH 26‑5 is fully compatible with the GTN family of carbide inserts, which are widely used in turning, milling, and drilling applications. Its slot width of 5 mm aligns perfectly with the standard GTN insert holder, allowing for rapid tool change without the need for additional adapters. The blade’s overall length of 26 mm provides sufficient clearance for deep cuts while maintaining a low center of gravity that reduces vibration. The design also incorporates a recessed rear surface that protects the insert shank from accidental impact, extending the service life of both the blade and the insert. When paired with Dorian Tool’s SGIH 26‑3 or other SGIH series blades, users can create a modular cutting system that covers a broad spectrum of machining tasks with minimal inventory.

In practical use, the SGIH 26‑5 delivers a noticeable reduction in cutting forces compared with conventional solid‑cut blades, translating into lower power consumption and reduced heat generation at the workpiece. The slot‑grip mechanism distributes load evenly across the insert, minimizing the risk of chip welding and tool breakage. Operators report smoother chip evacuation and a cleaner finish on steels ranging from mild carbon to hardened alloy grades. Because the blade maintains its geometry under prolonged exposure to cutting temperatures, it helps preserve the intended rake and clearance angles of the GTN insert, which is critical for maintaining dimensional accuracy in tight tolerance parts. The result is a higher first‑pass yield and less re‑work, delivering tangible cost savings on high‑volume production runs.

Each SGIH 26‑5 blade is individually wrapped in a moisture‑resistant sleeve to protect the steel surface from corrosion during storage and transit. The sleeves are then placed in a recyclable cardboard box that includes a concise installation guide and a QR code linking to Dorian Tool’s online technical library. The product is stocked in Dorian Tool’s central distribution center and ships within 24 hours of order placement, ensuring that manufacturers can replenish their cutting tool inventory without delay. For customers who require larger quantities, bulk packaging options are available, offering additional cost efficiency while maintaining the same level of protection for each blade.

The manufacturing process adheres to RoHS and REACH guidelines, ensuring that the SGIH 26‑5 blade is free from hazardous substances and safe for both operators and the environment. Dorian Tool sources its steel from certified suppliers who practice responsible mining and recycling, reducing the overall carbon footprint associated with blade production. This commitment to regulatory compliance and environmental stewardship makes the blade a responsible choice for manufacturers seeking to meet sustainability targets.

For applications that demand specialized dimensions, Dorian Tool offers a limited‑run customization service. Customers can request alternative slot widths, blade lengths, or edge radii to match unique machine tool interfaces or proprietary insert geometries. The engineering team works closely with the client to prototype and validate the modified design, guaranteeing that performance standards are maintained while providing a tailored solution that fits seamlessly into the existing workflow.

Usage

The SGIH 26‑5 excels in CNC turning operations where high spindle speeds and rapid feed rates are required. Its slot‑grip design locks the GTN insert firmly in place, allowing the machine to maintain consistent tool paths even under the dynamic loads generated by aggressive material removal. This makes the blade suitable for machining shafts, cylinders, and complex contours in automotive and aerospace components, where surface finish and dimensional precision are critical.

In manual machining environments, the blade’s compact size and easy‑to‑install slot provide a quick changeover for technicians working on job‑shop fixtures. The reduced weight of the blade compared with solid‑cut alternatives eases handling and reduces operator fatigue during extended machining sessions. It is also well‑suited for spot‑cutting and part‑off applications where precise length control is essential.

The blade’s durability enables it to perform reliably in harsh industrial settings, such as metal‑fabrication shops that process stainless steel, high‑strength alloy, and heat‑treated materials. Its resistance to chip adhesion and built‑in chip‑breaker geometry help maintain a clear cutting zone, preventing workpiece damage and extending tool life. Users can therefore rely on the SGIH 26‑5 for continuous production lines that demand minimal downtime.

The blade’s design also integrates smoothly with modern CNC control software that supports tool‑life monitoring and adaptive feed rate adjustments. By feeding real‑time data on cutting forces and temperature back to the controller, the SGIH 26‑5 enables predictive maintenance strategies that further reduce unplanned downtime. This synergy between hardware and software is especially valuable in high‑mix, low‑volume production environments where flexibility and efficiency are paramount.

FAQ

Can the SGIH 26‑5 be used with other insert families besides GTN?

While the blade is optimized for GTN carbide inserts, its slot dimensions are compatible with several other standard insert families that share the 5 mm slot width. However, performance may vary, and Dorian Tool recommends confirming fit and clearance with the specific insert manufacturer before use.

What is the recommended cutting speed range for this blade?

For most carbon and alloy steels, a cutting speed of 120–180 m/min provides optimal results. When machining harder materials such as stainless steel or hardened alloys, reducing the speed to 80–120 m/min helps maintain surface finish and prolong tool life.

How should the blade be stored to maintain its hardness?

Store the blade in a dry environment, preferably in its original moisture‑resistant sleeve, and keep it away from direct sunlight or extreme temperature fluctuations. Using the provided protective packaging helps prevent corrosion and preserves the heat‑treated hardness.

Is there a warranty or guarantee for the SGIH 26‑5 blade?

Dorian Tool offers a one‑year limited warranty covering material defects and manufacturing errors. Customers can contact the support team with the original purchase documentation to arrange a replacement or repair under the warranty terms.
