CNC Machining Center BT30 ER20 90° Angle Head Side Milling Head 360° Rotation

BT30 ER20 90 Degree Angle Head for CNC Machining Centers

This BT30 ER20 angle head mounts in a CNC machining center spindle to drive side milling and angular cutting at 90 degrees, turning a vertical spindle into a right-angle workhorse.

Overview

This 90 degree angle head is a spindle-driven attachment that redirects rotary power at a right angle for side milling, slotting, and angular feature work on a CNC machining center. The ER20 collet chuck grips a range of small-diameter tooling, and the head rotates 360 degrees so you can index the cutting direction without re-fixturing the part. It suits machinists running BT30 spindle machines who need to reach part faces the standard vertical setup cannot touch.

Built For Performance

• BT30 taper shank matches the machine spindle interface for direct mounting
• ER20 collet chuck accepts a broad range of shank diameters in one holder
• 90 degree output orientation enables side milling and angular cuts
• 360 degree rotation lets you index the head to the required cutting direction
• Precision-ground body and spindle for accurate angular positioning
• Compact head profile improves clearance in tight part zones

Specs At A Glance

Good To Know

Q: Does this angle head work on any BT30 machine? A: It is built for CNC machining centers with a BT30 spindle interface, so confirm your machine's taper before ordering. Spindle speed and feed limits for angle heads should be checked against your machine and tooling.

Q: What tooling fits the ER20 chuck? A: The ER20 collet accepts a range of shank sizes within its gripping capacity, so match the collet size to your cutter shank. Confirm the tool diameter and load suit the head's rated capacity.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
