Coba-Tech 4-6 TPI Holesaws (price is for 1 saw only)

German made Coba-Tech™ 4-6tpi (teeth per inch) Hole Saw.

Coba-Tech™ Bi-Metal Hole Saws are constructed of hardened, heat and abrasion resisting high speed steel teeth with a tough alloy body and cap. This gives them excellent strength, durability and shatter resistance. They will cut mild steel, aluminium, stainless, 4130 and T45. 

These 4-6tpi (teeth per inch) are perfect for heavier wall 2.0mm upwards. If your material is thinner choose the fine tooth 8/12tpi versions.

Remember to keep the speed slow (300rpm which is appox. half trigger on the slow setting of a battery drill) and use a thick cutting lubricant such as Rocol RTD or a tapping oil / paste. DO NOT USE WD40 as it will encourage rub and does not enhance cutting. These holesaws will fit all standard type Starrett, Morse etc Arbors. Holesaws up to 32mm fit straight on to the tube notcher arbor and 33mm upwards use the thread adaptors. All our Tube Notchers come with screw on thread adaptors for these larger sizes.

If you are using for cutting sheet in conjunction with a standard drill arbor with a pin drive, we recommend that you pull the collar back and screw all the way to the stop. Pin drives rattle and serve no purpose other than easy of removal. Also, take out the drill and fit the a piece of 6mm solid bar in place. The drill will vibrate and open up the hole which makes a mess of the process. Drill and 6mm piot hole first, then swap to the holesaw fitted with the solid pin.

Another good tip for using on thick sheet is to drill and exhaust hole just inboard of the hole. This lets the material expel down instead of clogging up the holesaw. This works on wood too using our courser toothed 4/6 tpi saws.

For thin sheet work we recommed Q-Max or Alfra hole punches for a perfect hole every time.
