Reamer Bits: Crafting Excellent Quality

RNK's reamer bits are tools specifically designed for enlarging existing boreholes. It typically combines axial force and rotational force, using carbide or steel cutting edges to rotate and cut through materials, thereby enlarging the hole and improving its precision and smoothness. The reamer bits are widely used in the processing of various hard materials such as metal, concrete, and stone. In industries such as construction, mining, and salvage, the reamer bits can be used for precise hole-making operations on walls and floors.

Working Principle of the Reamer Bits

The working principle of the reamer bits is based on the combination of axial force and rotational force. During operation, the drill bit cuts through materials with its rotating cutting edges while being subjected to axial thrust, gradually enlarging the existing borehole diameter. The design of the cutting edges typically includes multiple cutting teeth to efficiently remove material and ensure the hole's precision and smoothness.

Types and Structure of Reamer Bits

Types

There are various types of reamer bits including integral, welded, and indexable insert types. Different types of reamer bits are suitable for different processing needs and materials.

Structure

The reamer bits mainly consist of cutting edges, chip flutes, and a shank. The cutting edges are responsible for cutting materials, the chip flutes are used to discharge chips, and the shank is used to connect the drill bit to the drilling machine or handheld tool.

Precautions for Using Reamer Bits

Select the appropriate drill bit

Choose the right reamer bits according to the hardness of the processing material and the required borehole diameter.

Keep the drill bit sharp

Regularly inspect and replace worn cutting edges to ensure processing accuracy and efficiency.

Control cutting parameters

Set reasonable cutting speed, feed rate, and cutting depth to avoid drill bit damage and maintain processing quality.

Pay attention to cooling and lubrication

During processing, promptly add cooling fluid or lubricant to reduce cutting temperature and friction wear.
