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

An industrial long-shank carbide burr built for deep recesses, cast cavities and areas a standard-length tool cannot reach. The extended shank is a single steel stem brazed to a carbide head; the head shapes in the set cover cylinder, tree, cone, ball and flame profiles.

How It Works

Reach is bought at the cost of rigidity. As overall length grows, the safe operating speed falls and the allowable side load drops; the operator trades speed and feed for access. Shorter reach should always be chosen when the feature allows it.

Applications

Foundry cavity cleanup, deep cast recesses, weld roots inside frames, mould and die deep pockets.

Field Cases

• Foundry: a deep cast recess was cleaned without dismantling the fixture.
• Fabrication: weld roots inside a box frame reached from one open end.
• Die shop: a deep pocket floor dressed with the shortest tool that still reached.

Performance Data

Suitable Materials

Cast iron, carbon and alloy steel, stainless steel, aluminium castings and hardened tool steel.

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: Reach Classes: 100 / 150 / 200 / 300 mm

What extra reach costs. Typical industry practice; exact limits depend on shank diameter and machine:

Delivery Scope

Single burr or assorted head set; shank diameter and overall length confirmed with the order.

Why Choose VPOINT

Reach is treated as a stated parameter with a speed trade-off, not just a longer version of the same tool.

Precision & Quality Control

Braze concentricity, shank straightness and head runout checked per lot with ISO 9001 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.
