Description

BEYOND SRACR2020K12 Indexable Round Insert Turning Tool Holder

Product Overview

"Which tool holder is best for high-feed profile turning and heavy-duty copy machining?"

The SRACR2020K12 is the professional's choice for complex profile turning. Specifically designed to house RCMT12 (Round) inserts, this tool offers unmatched edge strength. Because the round insert geometry lacks weak points or sharp corners, it provides a superior surface finish and can withstand significantly higher feed rates. This makes it the ideal solution for large-radius contours, roughing operations, and precision copying.

Key Features

  • ✅ Round Edge Strength: RCMT inserts provide the strongest cutting edge available for interrupted cuts.
  • ✅ Multi-Directional Machining: Allows for versatile copy turning and profiling with 360-degree edge utilization.
  • ✅ Vibration Dampening: Forged from premium 40Cr alloy steel, heat-treated to HRC 42-45 for stability.
  • ✅ Precision Clamping: The screw-down mechanism ensures the round insert remains locked under high cutting forces.

Frequently Asked Questions

Q: Why choose a round insert over a square one?
A: Round inserts have no corners to chip, making them much stronger for heavy roughing and profiling complex radii.
Q: Are the screws and wrenches included?
A: Yes, every BEYOND tool holder includes the necessary mounting screw and wrench.
Q: Can I use this for aluminum machining?
A: Absolutely. Pair this holder with RCGT-type polished inserts for high-efficiency aluminum turning.

💡 Material Selection Tip: For Steel (P), we recommend BEYOND BYM25 grade. For Stainless Steel (M), use our B10 nano-coating for optimal heat resistance.

Technical FAQ & Buying Guide

How do I choose the correct specification?

When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.

How can I check compatibility with my existing setup?

For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.

What quantity and price unit am I ordering?

Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.

How should I choose cutting parameters?

Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.

Are bulk discounts available?

Our automatic quantity discount is 6% off for 2–9 items and 12% off for 10 or more items, based on the total product quantity in the cart. Other offers may not combine with this discount; check the applicable offer conditions.

When will my order ship and arrive?

According to our shipping policy, orders are typically processed and shipped within 1–3 business days after confirmation. Delivery generally takes 5–20 business days, depending on your destination and shipping method. Customs clearance or unforeseen delays may affect delivery times. A tracking number is sent by email after shipment.
