Buyohlic Indexable Insert U Drill 18 MM II Weldon Shank II Through Coolant II 10 pcs Carbide Inserts Free (Dia 18 mm~5D~25 mm Shank)

A U Drill (also called as Indexable Drill) is a type of drill used in CNC/VMC machines to drill large diameter holes quickly and efficiently. 🛠️ Key Features of U Drills Insert-Based Tool: Uses indexable carbide inserts at the cutting edge, which can be replaced when worn — no need to sharpen the whole tool. High Feed and Speed: Designed for high-speed machining and deep hole drilling. Coolant Through Design: These U drills come with through-coolant holes to improve chip evacuation and tool life. Rigid Body: Typically solid and made for high-strength applications — minimizes deflection/vibration during drilling and hence are quite accurate. Double Cutting Edge: Unlike twist drills that cut with a single point, U drills often have two cutting inserts, balancing the cutting force and improving performance. Each drill requires two inserts; Replace just the inserts instead of the entire tool when the cutting edges wear down Usable in CNC machines with coolant through capabilities for efficient chip evacuation Can be used to drill holes with high accuracy and precision; Suitable for a wide variety of materials, including steel, hardened steel, tool steel, stainless steel, plastic, titanium, aluminum, brass, and bronze. Includes: 10 pieces suitable size inserts with every U drill order, that you will purchase from us. IMPORTANT TO UNDERSTAND:- Please choose L x D of drill size as it can change drilling capacity which is most important part of drilling. Example of above illustration: What does 2D, 3D, 4D & 5D mean? Answer: 2 x Diameter (D) will give you the maximum Drill depth you can achieve through that U drill size, So please chose very carefully from the drop down keeping in mind the Bore diameter, & depth of the drill that you wanted to make with it.
