Busch® Pointed Burs FIG 5 – 0.90mm (ISO #090) are specialist rotary tools crafted for refined jewelry detailing, engraving, and shaping work. Manufactured from premium tungsten vanadium steel, these burs offer exceptional hardness, wear resistance, and long-term cutting performance — even in demanding use. Featuring a 0.90mm diameter and a 42° pointed tip, this FIG 5-style bur is designed to reach tight zones and execute precise cuts in precious metals such as gold, silver, platinum, palladium, and high-grade alloys. The pointed shape makes it ideal for engraving, filigree, fine texturing, and micro-setting. Each bur is precision-machined with uniform fluting, ensuring smooth, controlled cutting with minimal vibration or chatter. This contributes to clean edges, reduced material stress, and greater control over delicate surfaces. The burs conform to ISO #090 standards, ensuring consistency in dimension and quality across professional tools. Key specifications include a 3/32" (2.34 mm) shank for compatibility with most rotary tools (micromotors, flex shafts, Dremel-style handpieces), and a total length of approximately 1‑3/4" (44.5 mm). Each pack contains 6 burs, allowing jewelers and engravers to maintain continuity in their workflow. For best results and extended tool life, it is recommended that users operate within the safe speed limits indicated on the packaging and apply a suitable lubricant (e.g., Busch Lube‑Stik) to reduce friction and heat.
Busch® Pointed Burs are offered in sizes from 0.60mm to 5.00mm, making them a versatile choice across a range of detailed jewelry operations. Engineered and made in Germany, these burs reflect Busch’s commitment to high precision, performance, and consistency.

How to Use:
-
Insert the bur securely into a rotary tool (e.g., Dremel, Foredom, micromotor, or flex shaft).
-
Set speed based on bur size and material being worked on.
-
Apply light, controlled pressure—let the bur cut without forcing it.
-
Use lubricant (such as Busch Lube-Stik or synthetic wax) to reduce heat, improve chip removal, and preserve cutting edge.
-
Stop periodically to clean away metal shavings or debris during longer sessions.
Safety Information:
-
Always wear protective eyewear when operating rotary tools.
-
Avoid contact with the rotating bur and never touch it immediately after use—it may be hot.
-
Store burs in a dry, protective container to prevent corrosion and maintain edge sharpness.
-
Clean burs using a soft cloth, mild soap, and water after each use—or use an ultrasonic cleaner for optimal maintenance.
