The TechCut 4x™ is a precision low speed saw designed to cut small or delicate samples that cannot tolerate increased heat from friction caused by high speed sectioning. A 3.5" color LCD touchscreen is used to control all functions with an intuitive interface optimized for efficiency. The pivoting cutting arm has adjustable weights to apply or counterbalance downward force to the sample during sectioning. Cutting fluid is drawn from the reservoir by the blade to cool the sample. With a 3" to 6" blade range, samples up to 2" thick can be sectioned. 

Cutting fluid enhances blade performance, extends blade life and minimizes material deformation by reducing heat during sectioning. Use Deli-Cut low speed cutting fluid for gravity-fed saws at full strength. Use Maxi-Cut or Lubri-Cut for speeds above 1,000 RPM, diluted 2-5% with water. Lubri-Cut has a low oil content and is easier to clean.

CBN Metal Bond - Recommended for low speed (<1,000 RPM) sectioning of ferrous metal alloys including steels, iron, cobalt, nickel and lead-based alloys. Resin Bond - Recommended for higher speed (>1,000 RPM) sectioning of ferrous metal alloys >50HRC/750 HV.

Diamond Metal Bond: High Concentration (HC) - Recommended for general laboratory sectioning, excluding ferrous alloys. Most commonly used at higher (>1,000 RPM) speeds. Low Concentration (LC) -  Recommended for sectioning very hard or brittle materials such as ceramics, silicon, glass and refractories where chipping and pullout need to be minimized. Most commonly used at lower (<1,000 RPM) speeds.

Diamond Resin Bond - Recommended for cutting hard, brittle or delicate materials including ceramics, carbides, composites and exotic metals where low heat generation or improved surface finishes are desired. Most commonly used at higher (>1,000 RPM) speeds.

Aluminum oxide - Recommended for cutting ferrous metals and super alloys, while silicon carbide is best used for cutting non-ferrous metals and alloys. They produce minimal odor, cut cool and are suited for higher speed sectioning on non-gravity-fed saws. Two arbor sizes are offered.

Diameter - Diameter, thickness and arbor hole information can be found in the table below.

Bond - Bonded blades are composed of an inner metal core and an outer rim. The rim consists of either metal or resin mixed with abrasive, cured under high temperature and pressure to bond the matrix together. Metal bonding offers long life and durability, while resin bonding creates less heat and provides better surface finish. Metal bond blades work best for low speed sectioning (~1K and lower). For high speed sectioning (>1K RPM) resin bond, plated and solid core blades are recommended. 

Type - Bonded blades feature an outer rim of (metal or resin) bonded abrasive to an inner metal core. Plated blades feature a single layer of coarse diamond on the outer rim of the metal core. Solid core blades feature an abrasive that is bonded solidly through to the arbor core.
