Diamond core drill bits for iron are produced in diameters from 14 to 160 millimeters. The main body is made from forged medium carbon steel C45. The cutting segment consists of 50/60 mesh industrial diamond grains in a metal matrix. This segment is bonded to the body using laser welding technology with 0.02 mm precision. The effective cutting depth of these bits is up to 40 millimeters in steel. Optimal rotational speed is set between 300 to 1000 RPM depending on diameter. Internal cooling with water or oil-emulsion solution is mandatory. This drill can create holes with H9 dimensional tolerance in steel up to 35 HRC hardness.
The bit structure features helical flutes with a 35-degree angle for rapid chip evacuation. Cutting edges are coated with TiAlN nanocomposite to reduce friction. This coating increases surface hardness up to 3200 Vickers. The drill shank is typically triangular or cylindrical with an h6 tolerance. Average tool life before re-sharpening is 400 to 800 holes in structural steel. The bit diameter deviation under standard conditions is less than 0.1 millimeters. This bit is designed for use with stationary grinders or pillar drill machines. Its performance results in a hole surface roughness better than Ra 6.3 micrometers.You can order and buy Diamond Core Drill Bit for Iron and Steel from Iran by contacting us through whatsaap and email.

How to Identify Drill Bit Quality
Drill bit quality can be assessed using precise engineering criteria. Inspecting the cutting edge morphology is the first step. The edges must be extremely sharp and free of any damage. The bit material is the next determining factor. High-Speed Steel HSS bits are suitable for mild steel. Cobalt or carbide grade bits are essential for hard materials. Measure the shank and tip geometry accuracy with a caliper. The shank diameter tolerance should not exceed 0.02 mm. Uniform coating and color indicate quality control. Finally, test actual performance on the target material. A quality bit produces a uniform chip without excessive force.
