WORKING WITH BORON STEEL

Over the past 25 years, OEM's have been systematically replacing mild steel components with a variety of stronger, lighter and more exotic materials. In the early 70's, vehicles were made of mostly mild steel but you begin to see the emergence of plastics as well as conventional High Strength Steels.
​
The 2 primary reasons to the change in materials used in vehicle structures are fuel economy and safety. OEM's are working very hard to squeeze more miles per gallon from their vehicles. In addition to better mileage, consumers demanded and govenments mandated safer vehicles. By combining mild steel to help absorb impact with High Strength Steels to protect the passenger cages, OEM's were able to achieve both objectives.
​
However, this also changes the repair methodology of a damaged vehicle. Body technicians are facing problems with removing spotwelds on these steels when they are damaged due to the their characteristics. Using ordinary drill bits purchased from hardware store just won't help them solve this problem. After each spotweld, technician needs to regrind the already blunt drill bits with a 4 inch grinder, hoping to get the right contour and cutting edge by the control of their hand and eye coordination. This decreases the work efficiency significantly as the time normally used to repair the structure of the car is replaced by drilling spotwelds and regrinding drill bits. It contributes to the overall increase in repair time, making even a thinner margin for workshops.
One of the solution is to use a Tungsten Carbide drill bit. An example of a tungsten carbide drill bit is the 3 fluted drill bit shown in the picture below. Tungsten Carbide drill bit was introduced for removing spotwelds on Boron steel, AHSS and HSS. It works and cuts well but due to its hardness and brittleness, it cracks and break sometimes during removal process. Furthermore, there isn't any grinders available that can regrind the 3 fluted drill bit.

Tungsten Carbide
BIC Tool.Co.,Ltd has succesfully replace the Tungsten Carbide drill bit with SP802, specially heat treated HSS 2 fluted spotweld cutter. SP802 has the strength similar to a Tungsten Carbide drill bit but less brittle. SP802 can last many times more than an ordinary drill bit, cuts well on boron steel and is able to be regrinded using S1000K grinder in less than a minute with high precision.
BENEFITS OF THE SYSTEM
- SOLVES TECHNICIAN'S PROBLEM IN DEALING WITH HARD STEEL SUCH AS BORON
- SAVES TECHNICIAN'S TIME IN SPOTWELD REMOVAL
- EFFORTLESS RESHARPENING OF CUTTER
- CUTTERS CAN BE RESHARPENED OVER AND OVER AGAIN. NO WASTAGE
- SAVES OVERALL REPAIR TIME, BETTER PROFITABILITY
