The Straight Collet (often referred to as C-Type or SC Collet) is a cylindrical collet designed specifically for use in Power Milling Chucks. Unlike ER collets which rely on a taper for closing, straight collets are compressed within the milling chuck bore, providing an incredibly strong and uniform grip on the tool shank. This design makes them the industry standard for heavy metal removal rates, large diameter drilling, and rigid milling operations.
Unmatched Clamping Force: The straight design and thick wall construction allow for significantly higher gripping power than ER collets, eliminating tool pull-out during heavy cuts.
High Rigidity & Stability: Minimizes vibration and chatter, resulting in better surface finishes and longer tool life, even under high cutting loads.
Precision Manufacturing: Ground to tight tolerances with a runout accuracy of ≤ 0.01mm, ensuring your heavy-duty operations remain precise.
Wide Size Range: Available in standard series C20, C25, C32, and C42, covering a wide range of tool shank diameters (Metric: 6mm-32mm; Inch: 1/4"-1 1/4").
Premium Material: Made from high-quality bearing steel (SUJ2) or spring steel (65Mn), heat-treated to HRC 56-60 for maximum wear resistance and elasticity.
We are a specialized manufacturer of precision machine tool accessories, offering direct factory access to high-quality straight collets.
Specialized Production: We understand the critical requirements of heavy milling. Our collets are tested for both runout and clamping force stability.
Competitive Pricing: By sourcing directly from our factory in Pingyuan, China, you avoid distributor markups and get the best price-performance ratio.
Comprehensive Inventory: We stock common sizes of C32 and C42 collets for immediate shipment to support your urgent needs.
One-Stop Sourcing: We also manufacture the matching Power Milling Chucks (BT30, BT40, BT50), allowing you to buy the complete tool holder assembly from a single reliable source.
Q1: What is the difference between a Straight Collet and an ER Collet?
A:Straight Collets (C-Type) are designed for Power Milling Chucks and offer much higher clamping force and rigidity, making them ideal for heavy roughing. ER Collets are tapered and more versatile, suitable for general-purpose drilling, reaming, and light-to-medium milling.
Q2: Do you offer OEM services for Straight Collets?
A: Yes! We can laser-mark your brand logo and part numbers on the collet surface. We also offer customized packaging solutions to match your brand identity.
Q3: What sizes do you have available?
A: We manufacture the full C-series range:
C20: For 20mm shank chucks (Clamping range: 6-16mm)
C25: For 25mm shank chucks
C32: For 32mm shank chucks (Clamping range: 6-25mm)
C42: For 42mm shank chucks (Clamping range: 6-32mm) We also offer inch sizes upon request.
Q4: Can I order a sample to test the clamping force?
A: Yes, we welcome sample orders. We are confident that our straight collets will meet your requirements for rigidity and runout. Please contact our sales team to arrange a sample.
