The Right Bur for the Job

Burs croppedChoosing the carbide bur that suits your needs…

Have you ever wondered which carbide bur is right for the job? There are tapered tip, round tip, pear shaped, long, short, large and small shaft sizes, etc. How are you supposed to know which one to use? Delta Kits is here to put your mind at ease.
As you have probably noticed, Delta Kits sells several types of carbide burs.

The Tapered Tip Carbide Bur (26020) is sized to match the tip of Delta Kits' Spring Hammer and Slide Hammer tools. Create the perfect sized drill hole for terminating or anchoring cracks. The Tapered .047 Carbide Bur has a Superior, Level 5 Durability Rating, making them the most popular bur we sell.

The Long Tapered Point .035 Carbide Bur and Long Tapered Point .039 Carbide Bur (26050 and the 26060) are for fast drilling when smaller hole sizes are desired. These burs are virtually identical except for the tip size.

The Round Tip .039 Carbide Bur (26030 and 26085) is great for drilling the center of the impact point for improved resin flow and to clean out crushed glass or old resin from the pit area. Many technicians prefer round burs as they are easier to control and less likely to skip across the glass. The 26030 and the 26085 are the same bur, except that the 26085 has a larger shaft size and requires an 1/8” drill collet.

The Pear Shaped .024 Carbide Bur (26040) is the smallest bur we sell. Like the Round Tip .039 Carbide Bur, they are easy to control and skipping is minimal. Since the 26040 creates a small hole, the result is a less visible “scar” after the repair is completed.

Our rating scale of 1-5 is based on the average number of holes each bur is expected to drill before becoming dull.

26020 (Tapered, .047 inch hole size) – 5.0
26030 (Round Tip, .039 inch hole size) – 4.0
26085 (Round Tip, .039 inch hole size, .094 shaft diameter) – 4.0
26060 (Long Tapered Point, .035 inch hole size) – 3.6
26040 (Pear Shaped, .024 inch hole size) – 2.0
26050 (Long Tapered Point, .039 inch hole size) – 2.0

Which bur works right for you is largely personal preference, but understanding the differences and benefits of each will help make the decision easier.
