Diamond Core Drills - SMART CUT technology vs. Conventional metal bonded diamond drills

Diamond Core Drills with SMART CUT technology are the best value for users looking for high quality, and long lasting drills at an affordable price. The most fast drilling, highly aggressive, and longest lasting diamond drills available today. You can tell  Diamond Drills with SMART CUT technology apart from other drills, by the clean and smooth finish they leave behind. Unlike other diamond drills witch will work on some materials, and not on others. Diamond Drills with SMART CUT technology are the First diamond drills that will do an excellent job on just about any material. You can't beat their universal performance.

                          Sintered (Metal Bonded) Drills     vs.     Electroplated Drills

                               - Multiple layers of diamond                                           - Single layer of diamond

                               - Stands up well under aggressive conditions       - Cannot be dressed (in most cases)

                         - Super smooth finish                                      - Least Expensive

                         - Longest lasting Drill                                      - Shortest Drill Life

                         - Very Universal                                             - Cannot be used on some materials

                         - Most cost effective

Varying with application, an average electroplated diamond core drill will last you 80 to 120 holes. Whereas a conventional metal bond (sintered) diamond drill should last you about 1,200 holes. And a diamond drill with SMART CUTtechnology will last more than 2,000 holes (when used properly). Once you compare price and performance per hole, SMART CUT Metal Bond Diamond Drills (Universal Application) are the best alternative. 

Sintered (Metal Bond) Diamond Drills

Metal bonded diamond core drills have diamonds sintered and multiple layers of diamonds impregnated inside the metal matrix. Diamonds are furnaces sintered in a matrix made of iron, cobalt, nickel, bronze, copper, tungsten,  alloys of these powders or other metals in various combinations. Metal Bonded Diamond Tools are “impregnated” with diamonds. The compacted materials are then hot pressed or sintered to full density. Heating rate, applied pressure, sintering temperature and holding time, are all controlled according to the matrix composition. This means that selected diamonds are mixed and sintered with specific metal alloys to achieve the best cutting performance possible on any materials such as sapphire, advanced ceramics, optics, glass, granite, tile and etc. The metal bond surrounding the diamonds must wear away to continuously keep re-exposing the diamonds for the diamond tool to continue cutting. Sintered (metal bonded) diamond tools are recommended for machining hard materials from 45 to 75 on Rockwell Scale (5 to 9.5 on mohs scale of hardness). As a general rule of thumb, Metal Bond (sintered) diamond drills last longer than other diamond drills availableFind out more >>>

They can be used in almost all diamond drilling application ranging from very soft & abrasive materials to ultra hard materials. Typical applications include in order from hardness: Composites, Glass, Concrete, Sandstone/flagstone, Natural Stone, Optical Materials, Precious & Semiprecious stone, Advanced/Technical Ceramics, Ultra Hard & Brittle Materials, Advanced Materials, & Many Others. Sintered (metal bonded) diamond drills/bits are used & preferred in most Industrial/Manufacturing, R & D, Professional Contractor, & Serious Hobby Enthusiast / Craftsmen users. Sintered (metal bond) diamond core drills/bits are most widely used diamond drills across almost all industries & applications. They wear evenly, and are known for their long life & consistency.  

Precision & Accurate tolerances either on OD, ID, Run Out & Concentricity can only be obtained with sintered (metal bond) diamond drills. Sintered (metal bond) diamond core drills/bits Require PROPER USE & SOLID UNDERSTANDING of Proper Diamond Drill/Diamond Tool Principals. Experience well help as well. Careless handling or use in imprecise machinery will result in diamond drill wrecking/breaking, bending or cracking the bond and will prevent future use.

 Drilling life will vary with manufacturer & application/material factors described in this guide below. While there is no way to accurately predicting diamond drill life, with most conventional sintered (metal bonded) diamond drills, you can expect 350 to 1200 holes, parts machined, or cores. In laboratory tests, Diamond Drills with SMART CUT technology have shown to last 2,000+ holes on many applications/materials. Sintered (metal bonded) diamond core drills/bits with SMART CUT technology are the latest technology available in diamond drills. And represent the best value and performance per hole or part. They are the best investment you can make. Although they will cost you more than electroplated diamond drills, metal bonded diamond core drills will more than pay for themselves in terms of:

Longer Life

Electroplated drills cost less, and at first glance may seem like the most cost effective alternative. However, they will cost you more in the long run. Depending on material and application, metal bonded diamond core drills will last significantly more than 20 electroplated diamond drills put together. You can't get more life out of any other drill. Instead of constantly putting diamond core drills on and off your drilling machine, you will save time and money by using one drill. This means cost per hole, metal bond diamond core drills are the best choice. 
More Consistent performance

Electroplated drills have only one layer of diamond coated on metal core. Diamonds sit only on the surface. When this diamond portion is peeled off, the diamond drill will slow down, drill on the side (not drill straight) or stop working (drilling) altogether. Metal bonded diamond core drills have diamonds sintered and multiple layers of diamonds impregnated inside the metal matrix. Unlike electroplated drills, metal bond diamond core drills wear evenly, and are known for their consistency. You will get consistent drilling speed, and overall consistent performance from sintered (metal bonded) diamond drills.
