Burs & Drills

Remove material quickly and precisely with rotary burs and drills. Choose from among vanadium and hss burs from Busch, diamond grinding points, wax burs, and complete drill bit sets.

Vanadium Steel Burs
Economically priced vanadium steel burs cut precisely when new, but don't retain their sharpness as long as hss and carbide steel. Typically used at low speeds on a variety of metals.
High Speed Steel Burs

High Speed Steel (HSS) burs strike a good balance between cost and durability. They maintain their hardness (temper) better than Vanadium Steel and cost less than Carbide Steel.
Carbide Steel Burs

Carbide steel burs are the most durable but also the most expensive. They maintain sharp edges longer than other steel, even when used at high speeds.
Diamond Burs

Diamond burs/points are made from steel that has diamond particles bonded to the outside. They're ideal for carving glass, stone, and metal and are always used with water or a lubricant.
Wax Burs

Wax carving burs feature widely-spaced cutting edges for aggressive material removal without clogging. They can also be used for carving wood, plastic, and other soft materials.
Bur Sets

Contenti carries bur sets in a variety of assortments and size ranges for needs such as stone setting, wax working, and drilling. Most are made of economically priced vanadium steel.
Bur Accessories

Keep your burs and drills organized with a wood bur box or economical plastic organizer and keep them cutting clean and efficiently with beeswax or liquid bur lubricant.
Drill Bits & Taps

Steel twist drill bits for metal are available both individually and in sets. Standard, metric, and wire gauge sizes. Small tap and die sets for creating threads in metal.
Drilling Devices & Fixtures

Drill bits can be used in hand-held devices or in bench-top drill presses for greater control and precision. Contenti carries both.
