Diamond Bottoming Drills, also known as Flat Bottom Tip Drills, Bottoming Drills, Disintegrating Diamond Core Drills, or Diamond Offset Style Core Drills, utilize a sintered (metal bond) to offer unparalleled precision in drilling. These specialized tools are essential for creating blind holes in hard materials ranging from sapphire and quartz to slate, without leaving a core behind.
Designed for creating flat-bottomed holes or features in a variety of ultra-hard and brittle materials. Unlike standard drills that produce conical or pointed holes, bottoming drills have a flat cutting surface at the tip, allowing for the creation of clean, even bottoms in drilled holes. This design makes them ideal for applications where a precise, flat-bottom finish is required, such as in countersinking flat surfaces, milling pockets, or producing specific hole geometries in advanced materials.

These drills uniquely function both as a drill and a grinding disc, allowing them to not only create holes but also to grind the bottom and interior sides of these holes to a flat and smooth finish. This dual functionality is especially critical for drilling blind holes larger than 3/8" OD (outside diameter), which is a task beyond the capabilities of most standard drills.
Designed to deliver coolant directly through the center via a slot on the side of the diamond section or through a specifically designed hole, these drills ensure continuous lubrication and cooling during operations. This feature helps in maintaining the integrity of both the drill and the material being worked on, minimizing heat-induced damage and wear.
The grinding mechanism of these drills ensures high-quality surface finishes within the drilled holes, reducing the necessity for further finishing processes. This efficiency not only saves time but also enhances the overall quality of the workpiece.
Efficient Material Removal: Allows for quick removal of material without core retention.
Enhanced Precision: Ideal for creating flat-bottom holes and precise endpoints.
Versatile Applications: Suitable for various industries including electronics and engineering.
Reduced Waste: Minimizes material wastage, crucial when working with valuable substrates.
Adaptable to Various Materials: Effective on a wide range of materials from metals to ceramics.
If you are only drilling partially through a material, using a hollow diamond core drill might not be the best option. This type of drill can trap the core—the cylinder of material removed during drilling—inside the hollow drill bit if you don’t drill all the way through. Removing a trapped core can be difficult and may even damage the drill bit.
In these cases, a non-core formation diamond drill (solid drill) is usually a better choice for several reasons. Firstly, it grinds away the entire volume of the hole without producing a cylindrical core, so there's no worry about material getting trapped inside the drill. Secondly, a solid drill offers more precise control over the depth of drilling, particularly when used with a drill press or other machinery equipped with depth stops or measurements. Lastly, solid drills tend to produce a smoother finish in the hole, which is beneficial if the partial hole will be visible or used in a precision application.
However, if there's a specific need to extract a partial core from a material, a hollow core drill would be used, but it would require a method for core removal from the bit afterward. This scenario is less common but does occur in some research and specialized material analysis applications.
