CNC 50 TAPER CT TOOL HOLDERS ER-16

Upgrade your CNC machining performance with high‑precision 50 taper CT tool holders with ER‑16 collets — engineered to deliver secure tool gripping, smooth operation, and reliable performance across a wide range of milling, drilling, and finishing applications. These collet chuck tool holders are essential for any shop, production line, or custom machining setup using a CAT50 / 50 taper machine spindle.

🔩 What Are 50 Taper ER‑16 Tool Holders?

50 taper tool holders with ER‑16 collet chucks are CNC tooling devices that mount directly in the CAT50 or similar 50 taper spindle. The ER‑16 collet system allows quick and secure clamping of cutting tools — including end mills, drills, taps, reamers, and step tools — with a gripping range typically up to ~10 mm. These holders rely on the widely accepted DIN 6499 / ISO standard ER system for true interchangeability and compatibility with a variety of collets and tooling.

🛠️ Key Features & Benefits

✔ Superior Precision & Runout Control

High‑quality holders are precision ground and balanced to reduce run‑out, ensuring tool concentricity and better surface finishes on milled features. High tolerances are critical for smooth spindle operation and consistent results.

✔ ER‑16 Collet System

ER‑16 collets provide a wide clamping range for tool shanks (typically up to ~10 mm) and offer uniform 360° gripping force through axial tightening. This translates into secure tool holding, reduced slippage, and improved tool life.

✔ Quick Tool Changes

The standard ER collet system allows fast collet swaps and tool changes, improving uptime and productivity — essential for high mix or small‑batch CNC operations.

✔ Balanced for High‑Speed Machining

Quality holders are dynamically balanced to industry standards (e.g., G2.5 at high RPM) to minimize vibration, protect spindle bearings, and enable higher spindle speeds without compromising finish quality or tool life.

✔ Durable Alloy Steel Construction

Manufactured from hardened alloy steel with precision tolerances, these holders stand up to heavy cutting loads, repeated torque, and frequent changes without degrading performance.

⚙️ Applications

50 taper ER‑16 tool holders are essential for:

• Precision CNC milling and finishing operations
• Drilling and reaming tasks with small‑shank tooling
• Light to moderate material removal in aluminum, steel, and composites
• Production, prototyping, and job‑shop environments
• Workholding where quick collet changes and tool versatility are needed

📈 Why Choose Quality ER‑16 Tool Holders

Using appropriately sized and balanced tool holders improves machining accuracy, surface finish, and spindle life. The standardized ER system helps shops maintain flexibility, reduce tooling inventory costs, and support multi‑brand machine compatibility.
