Micro Drills
SMART CUT® CVD diamond micro drills are used for drilling micro holes in large variety of hard and brittle materials such as sapphire, high density ceramics, micro-circuit substrates, glass, silicon, various wafers, substrates, tubes etc We offer large variety of standard stock & custom micro drills from 0.05mm diameter to 6mm. with 3mm and 3.2mm shanks, and various heald lengths from 0.5mm and up, and flute specifications.
PCD (Polycrystalline) Micro Drills
Diamond Micro Drills
SMART CUT® PCD (Polycrystalline Diamond) Micro Drills are precision-engineered tools designed for applications that demand exceptional hardness, wear resistance, and dimensional accuracy. They are available starting from 0.4 mm in diameter, with a wide selection of head lengths and standard shank diameters of 3 mm and 3.2 mm. Each drill features a sintered polycrystalline diamond tip bonded to a carbide or tungsten substrate, providing superior rigidity, heat resistance, and extended tool life. These micro drills are widely used in the semiconductor, electronics, EDM electrode manufacturing, and die and mold industries. In semiconductor production, they are used for machining monocrystalline silicon, inspection and cleaning jigs, and precision fixture fabrication. In EDM electrode manufacturing, they are ideal for drilling graphite electrodes and other hard-to-machine materials that quickly wear down conventional tools.
SMART CUT® 005DME MCDU
SMART CUT® 005DME diamond micro drills are produced using electroplated (nickel bond) galvanic plating process. These tools can be used for drilling and machining large variety of materials such as Precision Optics, Silicon Carbide, Boron Nitride, Boron Carbide, Alumina Ceramics, Silicon, Sapphire & Yag, Glass, Quartz, & Pyrex Tubing & Many Other Applications.
Small diameter below .020” (0.5mm) are made using diamond plating (galvanic) method, where the diamond crystals are deposited evening on the tip evenly over time. The steel body using is usually high speed steel ranging in hardness from 40 to 50 Rockwell scale C. Precision tolerances are maintain on diameter.
SMART CUT® 010DME (SMCDU)
SMART CUT® 010DME diamond micro drills are produced using electroplated (nickel bond) galvanic plating process. These tools can be used for drilling and machining large variety of materials such as Precision Optics, Silicon Carbide, Boron Nitride, Boron Carbide, Alumina Ceramics, Silicon, Sapphire & Yag, Glass, Quartz, & Pyrex Tubing & Many Other Applications.
Small diameter below .020” (0.5mm) are made using diamond plating (galvanic) method, where the diamond crystals are deposited evening on the tip evenly over time.
The steel body using is usually high speed steel ranging in hardness from 40 to 50 Rockwell scale C. Precision tolerances are maintain on diameter. Diamond sizes used range form 6 microns to 120 microns. Head length made in proportion to diameter of the tool. Usually it cannot exceed 15 times the diameter of the tool. Diamond grit size used in in proportion to diameter of the drill tip and can range form 3 to 70 microns. shank size is usually 1/8” (3.2mm) or .040” (1mm).
