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