Design and Construction — a VPOINT long-shank carbide burr for deep cavities and reach work, sized for steel / stainless welds and similar work. YG8 carbide at HRA 89–91; die-grinder reference speeds are in the performance table below, with the flute-style guidance in the FAQ. ISO 9001 production, batch-verified, custom sizes from drawings.

Design and Construction

A standard double-cut long-shank carbide burr. The double-cut flute pattern breaks chips into small segments, which matters most in a deep recess where a long chip cannot escape past the head and shank.

How It Works

In a deep cavity the cut is limited by chip removal rather than by spindle power. Air blast, vacuum extraction and periodic pecking are the three practical routes; the double-cut pattern makes all three more effective by shortening the chip.

Applications

Deep pocket deburring, cast recess cleanup, internal weld dressing, enclosed cavity work.

Field Cases

• Foundry: air blast through the cavity kept the flutes clear on a deep recess.
• Fabrication: short peck cycles prevented chip packing on an internal weld.
• Die shop: vacuum extraction kept the working area visible during a long pass.

Performance Data

Suitable Materials

Cast iron, carbon and alloy steel, stainless steel, aluminium and non-ferrous alloys.

Standard reference values for guidance only — always adjust to the workpiece material, the machine spindle speed and the feed, and confirm on the actual part.

Material Comparison: Chip Evacuation: Air Blast vs Extraction vs Pecking

Three routes for clearing a deep cavity. Typical industry practice:

Delivery Scope

Single burr; head shape, shank diameter and reach confirmed with the order.

Why Choose VPOINT

Deep work fails on chip packing, not power – the flute pattern and evacuation route are stated together.

Precision & Quality Control

Flute geometry, braze concentricity and head runout verified per lot with full batch traceability.

Frequently Asked Questions

How deep can the long-shank version reach?

100, 150, 200 and 300 mm reach classes — pick the shortest reach that gets you there, because reach amplifies any collet runout.

How do I keep it from chattering?

Seat the shank fully, use light pressure, and let the flutes clear — long tools punish heavy hands.

Same head codes as standard burrs?

Yes — SA–SM contours carry over, so a long-shank burr matches the shape you already run on short shanks.
