Rotary Carbide Burr for Metal GEKO G37514 — 12×25 mm, 6 mm Shank, Face and Side Cutting

GEKO rotary carbide burr G37514 is a tungsten‑carbide cutting tool designed for metalworking tasks. The burr has a 12×25 mm cylindrical head with face-and-side cutting geometry and a 6 mm straight shank that fits standard rotary tools and die grinders. It is suitable for shaping, deburring, slotting and finishing operations on steel and various non‑ferrous metals, providing consistent material removal and a controlled cutting action.

Advantages

The solid tungsten‑carbide construction offers high wear resistance and maintains cutting performance under prolonged use. The face-and-side cutting profile enables effective material removal both on the end face and along the side of the head, reducing the need to change tools for different operations. The 6 mm shank ensures compatibility with a wide range of rotary tool collets and die grinder chucks, allowing stable, concentric rotation and improved control during precision work.

Suitable for

• Shaping and profiling metal workpieces
• Deburring welded joints and cut edges
• Slotting and enlarging holes or grooves
• Surface finishing and smoothing of steel and non‑ferrous metals
• Toolroom and maintenance tasks with rotary tools or die grinders

Key specifications

• Head size: 12 × 25 mm (diameter × length)
• Shank diameter: 6 mm (straight shank)
• Material: tungsten‑carbide
• Cutting type: face and side cutting profile
• Compatibility: fits standard rotary tool and die grinder collets that accept 6 mm shanks

How to use

Mount the burr securely in a compatible rotary tool or die grinder with a matching 6 mm collet or chuck. Check that the tool speed is appropriate for the work material and the burr size; begin at a moderate speed and adjust as needed to maintain clean cutting without excessive vibration. Apply light, steady pressure and use smooth passes across the work surface; avoid forcing the tool to prevent premature wear and breakage. For best results, maintain proper coolant or lubrication when machining heat‑sensitive alloys and stop periodically to clear chips from the cutting area.

Usage recommendations

Use personal protective equipment including eye and respiratory protection when cutting or deburring metal. Match speed and feed to the workpiece material: lower speeds for stainless steels and higher speeds for softer non‑ferrous metals. Replace the burr when cutting performance decreases or if visible damage appears to prevent compromised results.
