Specifications:

ER Collets: The most common, interchangeable with DIN 6499. Sizes vary from ER-8 to ER-50, with nominal diameters (mm) representing tapered receptacle sizes. Clamping range often decreases by 0.5-1 mm (up to 2 mm for ER-50) below nominal size. For example, ER-32 is compatible with shanks ranging from 2 to 20 mm.

There are Collect Chuck checklists

• TG (Tremendous Grip) Collet Chuck.

• DA (Double Angle) Collet Chuck

• 5C Collet Chuck

• Milling Collet Chuck (e.g., Side and Face Cutter Chuck)

• Quick-Change Collet Chuck

  General Details for Collet Chucks in Cutting Tools.

• Clamping range: is 0.5-34 mm (ER8-ER50), 1/16-1-1/8" (5C), or wider for proprietary systems.

• Runout: 0.0001-0.001" (2-25 µm), with high-precision ER or quick-change systems on the lower end.

• Max speed: 6,000-30,000 rpm, depending on chuck balance and taper (HSK is ideal for high speeds).

• Taper types include: CAT (40, 50), BT (30, 40, 50), HSK (A, E, F), SK, R8, MT, ISO, and Capto.

• Coolant delivery: options include through-tool (sealed collets), CoolFLEX, and external.

  
  Materials:
  

• Collets: are hardened steel (spring steel for ER and 5C) or carbide-lined for maximum torque.

• Chucks: are made of case-hardened steel or alloy to provide endurance.

• Gripping Force: Specialized nuts (e.g., Techniks PowerCOAT) provide up to 75% more grip.

• Balance: G2.5 or higher for high-speed chucks (e.g., HSK at 25,000 rpm).
  

  Special Features:

• Anti-vibration designs (such as Rego-Fix powRgrip).

• Adjustments for concentricity are preset (for example, Set-Tru).

• Sealed nuts withstand coolant pressures up to 100 bar.

Coolant Systems

Through-Tool Coolant (Internal Coolant Delivery)

Specifications:

Pressure: 20-100 bar (e.g., Techniks CoolBLAST ER chucks at 70 bar).
Collet types include ER (sealed, 0.5-20 mm), TG (6-25.4 mm), and Rubberflex (4-60 mm).
Tapers include CAT, BT, HSK, SK, and Capto (HSK-A suited for through-coolant).
Coolant types include water-based, oil-based, and MQL (minimum quantity lubrication).
Maximum speed: 30,000 rpm (e.g., HSK63A with coolant).

There are coolant system checklists:

• CoolFLEX Coolant Delivery

• External Coolant (Flood or Spray)

• Minimum Quantity Lubrication (MQL) Coolant System

• Through-Tool Coolant System

• Cryogenic Coolant System

General Specifications.

• Coolant Pressure: Through-tool: 20-100 bar.

• External: 5-20 bar.

• MQL: 10-30 bar.

• Cryogenic pressures range from 10 to 50 bar.

  Coolant types:

• Water-based: synthetic emulsion (external, through tool).

• Oil-based: Straight oils and MQL mist.

• Cryogenic gases include LN₂ and CO₂.

• Air: oil mist (MQL).

• Flow rate: 10-100 L/min through the tool or externally.

• MQL: 10-100 mL per hour.

• Cryogenic rate: 0.5–2 kg/min.

• Maximum speed ranges from 10,000 to 30,000 rpm (MQL and through-tool are the highest).
  

  Tool Compatibility:

• Through-tool/Cryogenic: Tools equipped with coolant channels.

• External/MQL: Any tool, but MQL likes coated ones.

• Tool materials include carbide, HSS, cobalt HSS, CBN, PCD, and coatings (such as TiAlN and AlCrN).

  Special Features:

• Through-tool: Improved flute design for chip removal.

• MQL: Low-friction coatings that improve mist efficiency.

• Cryogenic tool geometries are those that are thermally resistant.

• External: Full compatibility with conventional tools.

Cutting discs come in a variety of types and specifications, depending on the material to be cut and the equipment utilized. The following is a general guide to the types, specs, and common applications of cutting discs.

Types of Cutting Discs:

1. Metal Cutting Discs
   Suitable for cutting steel, stainless steel, and ferrous metals.
   For example, A24R is an aluminum oxide-based disk.

2. Stone Cutting Discs
   Used to cut concrete, masonry, bricks, and tiles.
   Made of silicon carbide.

3. Diamond Cutting Discs
   To cut hard materials such as ceramic, granite, and reinforced concrete.
   Have a diamond-grit edge (sintered, segmented, or continuous).

4. Multipurpose Cutting Discs
   Designed to cut through various materials such as wood, plastic, and metal.
   Typically carbide-tipped or diamond-coated.

5. Inox Cutting Discs
   Specially designed for stainless steel (Inox), it reduces heat and prevents corrosion.

6. Slitting/Thin Cutting Discs
   Thin profile (usually 1.0mm or 1.2mm).
   Suitable for quick, precise cuts with minimal material loss.

🔹 Tips for Selecting the Right Disc

• Aluminum oxide is suitable for general metals.

• When working with stainless steel or hardened metals,

• Use zirconia alumina or ceramic.

• Silicon carbide is suitable for stone and concrete.

• Thin discs (1.0-1.6 mm) are ideal for making faster, cleaner cuts.

• Always match the disc's RPM rating to your grinder's speed.
