FAST U-drill, also known as U-drill, down hole drill, brute force
drill, spray drill, internal cooling drill, and reaming drill. The
advantages of using it in machining centers or CNC lathes are high
machining efficiency, simple operation, and relatively low cost.
1. The processing efficiency is generally 2-3 times that of the
Fried Dough Twists drill.
2. U-drills can be directly machined on workpieces without the need
for center drills to drill guide holes.
3. The front end of the blade body is equipped with replaceable
blades, which reduces the cost of use.
Center Drill Bit is a tool specifically designed for drilling
starting holes in materials, playing an important role in machining
high-precision or deep holes. The following is a detailed
explanation about Center Drill Bit:
Definition and purpose:
Center Drill Bit is mainly used to pre drill a center hole or
positioning hole on materials such as metals, alloys, plastics,
etc., in order to use other drill bits or tools for deeper drilling
or processing in the future.
Design and features:
Shape: Center Drill Bit typically has a shorter length and smaller
diameter to accommodate the need to drill starting holes on the
material.
Structure: It consists of a drill tip, drill body, and handle. The
drill tip is used for cutting and positioning on materials, the
drill body provides strength and stability, and the handle is used
for connecting and fixing on the drilling rig.
Material: Usually made of hard alloy or high-speed steel to ensure
its hardness and wear resistance, and to maintain sharp cutting
ability during the machining process.
Usage scenario:
Center Drill Bit is widely used in fields that require
high-precision positioning or deep hole machining, such as
mechanical manufacturing, mold manufacturing, aerospace, etc. In
these fields, accurate starting holes are crucial for subsequent
machining.
Advantages:
High precision: Due to the design of the drill tip and the
selection of materials, the Center Drill Bit can accurately locate
and drill the starting hole, providing a good foundation for
subsequent processing.
High efficiency: Due to its shorter length and smaller diameter,
Center Drill Bit can quickly drill starting holes on materials,
improving processing efficiency.
Stability: The design of the drill body provides good stability,
making it less prone to deviation or shaking during the machining
process.
Size and type:
The Center Drill Bit has multiple sizes and types to choose from,
to meet different material and processing needs. The common size
range ranges from a few millimeters to several tens of millimeters,
and types include straight shank, tapered shank, etc.
Precautions for use:
Before using the Center Drill Bit, it is necessary to ensure stable
fixation between the drilling rig and the workpiece to avoid
deviations or shaking during the machining process.
During the machining process, it is necessary to control the
appropriate speed and feed rate to ensure the stability and
machining quality of the drill bit.
Regularly clean and lubricate the Center Drill Bit to extend its
service life and maintain machining quality.
Summary: Center Drill Bit is a high-precision and high-efficiency
drilling tool widely used in fields that require high-precision
positioning or deep hole processing. By selecting the appropriate
size and type, and following the correct usage methods and
precautions, it is possible to ensure optimal performance during
the machining process.
