What is swaging tool drill bit?

the swaging tool drill bit is made of strong steel and it is a kind of tube expander tool in the HVAC industry. the swaging tool drill bit is coupled to a electrical drill and works out great swage depth for perfect fitting.

The characteristic of swaging tool drill bit

 It creates a precise deep swage without wobbling or cracking that is easier to braze. It is designed for the most popular dimension tubes in the HVAC industry.

Heat by Friction – Preserves copper’s malleability during the molding process, avoid cracks and leaks

Fits into any Drill – Works efficiently along with the most common screwdrivers and drills, recommended using an electrical drill with power above 550W.

10X faster – Flares and swages in 5 seconds. Up to 10X faster than conventional tools.

Avoid Cracks and Leaks – The high-temperature process will assure a perfect fitting, the metal doesn’t crack.

410a Compatible – Tube walls thickness to withstand the high pressure of refrigerants more than 4.0MPA.

Various Dimension applicable – Designed for the most popular tubing diameters in HVAC.

Available models:

There are several models for options and used for different tube dimensions in repair air conditioner, metic and inch size are both available.

7 steps to perfectly work out the pipe expansion

1. Hold the tube from a safe distance 

please find a flaring tools kit which used to fix the pipes in a suitable dimension you are going to work on or your hands hold the tube, make sure to wear adequate protective equipment like professional gloves.

2. keep the tube aligned with the tool

Please make sure the tube and the swaging tool drill bit are on the same horizontal lines from the direction of our eyes.

Any tilt angle will cause the failure of pipe deep swaging, the right manner is important during the molding process.

 3. With the drill maximum speed on

we recommended using an electrical drill with power above 550W.hold on the tubes tightly by your hands or your fixing clip and insert the expansion pins into the tubes.  

4. Push the swaging spin all the way in

starting the electrical drill and push the swaging spin all the way in until the stopper hits the tubes. keeping the tube aligned with the tool during the deep swaging process along with the drill working out.

5. Pull off the spin tools from the tube

Keeping it Aligned and electrical drill or screwdrivers maximum speed on. when finished pull off the spin tools from the tube

6. crack-free and ideal depth swage for a safe fitting

The swaging sping tools will deliver a crack-free, ideal depth swage for safe fittings. a perfect fitting is produced by your hand, that is well done and joyful work.

7. Assemble the tubes 

After finishing the depth swage for tubing, assemble the tubes as usual. it is now ready for economic brazing. it is an easy operation guideline.

What is a flaring tool drill bit?

The flaring tool drill bit is a kind of tube flaring head tool and designed for pipe flaring in air conditioner installation and repair work. It is used for molding tubes using heat by friction Way more surface of contact between the flare and the valve

the feature of the flaring tool drill bit is the same as swaging tool drill bit like flares in 5 seconds, preserves copper and aluminum malleability while doing the flaring, avoiding cracks and leakages  

Available models:

Flaring tool drill bit containing 5 pieces in a set, with the following diameters: 1/4″, 3/8″, 1/2″, 5/8″, 3/4″, and 7/8″ (tube’s outer diameter). Capable of flaring Soft, and Hard, Copper, and Aluminum when coupled to a drill.

CT-900F-041/4″For tube’s outer diameter 1/4″100
CT-900F-063/8″For tube’s outer diameter 3/8″100
CT-900F-081/2″For tube’s outer diameter 1/2″100
CT-900F-105/8″For tube’s outer diameter 5/8″100
CT-900F-123/4″For tube’s outer diameter 3/4″100
CT-900F-147/8″For tube’s outer diameter 7/8″100
CT-900F1/4″ 3/8″ 1/2″ 5/8″ 3/4″containing an assembly of CT-900F-04,06,08,10,12,1420

4 steps to work out the pipe flaring

  1. Use a reamer to remove the burr on the inner wall of the pipe end, please take safety precautions during the whole process
  2. select the corresponding expansion pins and fix them on the electric drill, it is recommended to use an electric drill with power above 550W.
  3. fixed the tube, insert the expansion pins into the copper tube, start the electrical drill to expand the pipe
  4. Turn off the drill, remove the copper pipe and insert another copper pipe end
