Punch with the drill

Choosing which to use to drill different materials is not always easy. I propose here in brief a vast choice of possibilities to drill various materials with the drill. A good drill will certainly include:

• Swing effect, creates a vibration that makes it possible to pierce the walls more simply.
• Adjusting the rotation speed, generally the more a tip has a small diameter, the more it will have to turn quickly, the bigger it will be, the more it will have to turn slowly.
• Reverso, also turn in the opposite direction, useful in case it is used as a screwdriver.
• Clutch, adjusts the maximum torque, always useful for use as a screwdriver

Iron and Steel

• Carbon steel tips, suitable for soft metals.

• HSS high speed steel tips, high speed steel, suitable for hard metals.

• Titanium nitride tips, treated with this extremely hard ceramic material, improves cutting capacity and durability, they are also recognizable by their golden color.

Speed of rotation of drill bits for iron

Wood

• Wood drills, excellent for small diameters

• Mecchie, for larger holes

• 30mm hole saw, excellent for through holes on panels.

Concrete Masonry

• Two or four cutting edges with widia tips, are specific for masonry, activate the beating effect of the drill to drill more quickly and with less effort.

• Crown bits, cups for large diameters with widia inserts. If the tip is not enough and you want to make a clean hole, the cups are the right choice for you.

Stoneware, Stone and Glass Tiles

• Diamond tips for gress and stone, you can also use them on un-tempered glass. Don't press too hard for a safe hole. No knocking effect, cool with water.
