Diamond Conical Reamer FANAR 2–35 mm model 06986

FANAR diamond conical reamer model 06986 is a precision tool designed to enlarge and finish holes with a working range from 2 to 35 mm. The reamer has a tapered conical diamond-coated profile that provides controlled material removal and fine surface finish on hard materials where conventional HSS or carbide tools are inadequate. It is suitable for rotary drilling machines or hand-held reaming operations in construction, metal fabrication, stone and ceramic processing, and other applications requiring accurate bore sizing and smooth internal surfaces.

Advantages

The conical diamond surface offers uniform cutting action along the taper, enabling stepped or continuously adjustable bore diameters within the 2–35 mm range. Diamond abrasive provides high wear resistance and long working life on abrasive or hard substrates. The tool’s tapered geometry allows precise alignment and gradual enlargement of holes, reducing the risk of chipping or thermal damage. Its design supports use with standard rotary speeds and feeds for improved process control and repeatability.

Подходит для

• Расширение и финишная обработка отверстий в камне, керамике и стекле
• Обработка твердых металлических сплавов и абразивных материалов
• Использование с ручными и стационарными вращающимися инструментами
• Подготовка посадочных мест и точное доведение диаметра до заданного размера

Key specifications

• Working diameter range: 2–35 mm
• Conical tapered profile for stepped or continuous bore adjustment
• Diamond-coated abrasive surface for high wear resistance
• Suitable for rotary drilling machines and hand-held reaming
• Intended for use on hard, abrasive and brittle materials

How to use

Mount the conical reamer securely in the chuck of a rotary drilling machine or a compatible hand-held tool. Start with a pilot hole smaller than the desired final diameter, then apply steady, moderate feed while rotating at appropriate speed for the material. Use light coolant or water when processing stone, ceramic, or metal to reduce heat and remove debris. Advance the reamer gradually along the taper until the required diameter and surface finish are achieved, then withdraw the tool while maintaining rotation to avoid scoring the bore.

Usage recommendations

For best results, match rotation speed and feed to the workpiece material and use continuous coolant when machining abrasive substrates. Inspect the bore frequently during reaming to prevent over-enlargement. Replace the tool if diamond wear noticeably reduces cutting performance.
