Center Drilling Bits Effect on Different Materials?

There are many types of center drills bits

The main function of center drills is to guide twist drills bits for hole processing

The function reduces errors during processing and provides convenience for other drilling equipment

Earlier we introduced the type of center drill, click here know more!

The Center Drill Bit is Used to Drill the Center Hole of the Bench Drill

The pecking method is used, the feed amount should not be too large. With the bench drill, you can grasp the cutting amount at any time.There is no problem with drilling

If the two countersinks are to be coaxial, a very good reversing jig is required. It is not a problem of processing but a problem of clamping. Doing it on the machining center also depends on the fixture

If the position of the bench drill hole is strict, you can first clamp a pointed reamer or a pointed tip on the collet of the bench drill to hold the punched center hole, and then, or press to process work, or just change the drill bit directly

 

The Big Bit Adopts the Center Drilling Structure

It has a good centering effect, thereby ensuring good straightness of the hole position. The inside and outside blades adopt a replaceable smallholder structure

In actual use, the outer blade holder is more likely to be damaged. By replacing the small tool holder, the scrap of the whole drill is avoided, and the tool cost is saved

By adjusting the outer tool holder, the drill processing size can be changed within 0-5 mm; the tool head and tool holder adopt a combined structure

 

For Different Depths of Holes, You Only Need to Change the Shanks of Different Lengths

The drill has a central outlet hole, which can better cool the blades, extend the life of the blades, and facilitate chip removal

Indexable carbide inserts are used for cutting, with higher speed and feed, and the hole wall finish is greatly improved

During the processing, the iron chips are in the chip-breaking state, and there is no slender winding iron chips of the traditional twist drill, and the safety is greatly improved and the automatic continuous feeding does not need to retract the chips every time, and the efficiency is greatly improved

 

The Center Drill Bit is a Kind of Prefabricated Precise Positioning Instrument Used for Hole Processing to Reduce Errors

When finding a hole, when you are using a traditional drill, it will indefinitely find the position you are looking for

If that is the case, over time, human, material, and financial resources will continue to be consumed

 

How Can you Accurately Locate the Hole’s Destination?

A-type center drills can save workers from wasting time and manpower like traditional tools Material and financial resources can find an accurate location, and it is safe and not easily damaged, which can effectively ensure the safety of users during use

 

Before Machining the Center Hole, We can Flatten the End Face of the Shaft to Prevent the Center Drill From Breaking

Generally, the peak angle of the standard center drill is 118 degrees

In fact, the function of the center drill is not just a fixed point function
