The Thunderweb geometry allows faster chip ejection. It also dissipates heat better. These two features give greater drilling speed and longer drill bit life.
The parabolic section reduces the risk of the drill bit jamming in deep holes
The web is thicker and increases towards the shank (tapered web). The parabolic section offers greater strength, lower risk of breakage, excellent for particularly deep holes, longer life
Cutting angle: 135°.
Bright finish allows faster chip removal and longer drill bit life.
ABS case with rubber corners for greater durability.
Withstands high pressure loads.

SHOCKWAVE™ step drill bits are designed and engineered for use on impact drivers. The 1/4" hex shank with SHOCKZONE™ ensures maximum durability and prevents premature breakage of the connection.
Aluminium titanium nitride coating for up to 5 times longer life.
Double spiral flute: optimised for impact drivers.
RAPID STRIKE TIP™: centring point for better centring, with no need for a pilot hole.
Laser-etched diameters for better visibility, even in the long term.
Milwaukee 48899320 - Step drill bit 4 - 20 MM
Centring point for better centring, with no need for a pilot hole.
The tip geometry allows extremely precise drilling without leaving burrs and avoiding skipping that could damage the material.
Optimised 2-flute geometry with a very sharp edge that makes it up to 2 times faster.
Made from custom-engineered steel with a black obsidian coating for longer life, up to 4 times longer than conventional step drill bits.
Designed for use with the impact driver and
drills / drivers.
Hex shank up to 260mm length, three-flat shank up to
400mm length.
Tungsten carbide (TCT) cutting edge allows drilling into
concrete, bricks, roof tiles, concrete blocks, thin metal,
medium-soft ceramic tiles, all types of wood
and PVC.
White flute for easy identification.
STEP DRILL BIT UP TO 28.3 MM:
Step drill bits are ideal for drilling the following materials: - Ferrous and non-ferrous sheet metal, profiles and tubes. - Copper, brass and aluminium. - Steel
Electricians: drilling of panels and boxes for the installation of cable glands. - Plumbing / HVAC: access holes for pipes and installations
The main advantages over drilling with conventional drill bits are: with one step drill bit you can drill several sizes - Better for enlarging holes
Surface countersinking, drilling and deburring all in a single operation.
Centring point for better centring, with no need for a pilot hole.
The tip geometry allows extremely precise drilling without leaving burrs and avoiding skipping.
Optimised 2-flute geometry with a very sharp edge that makes it up to 2 times faster.
Made from custom-engineered steel with a black obsidian coating for longer life, up to 4 times longer.
Optimised for use with the high speeds of cordless tools.
Laser-etched diameters for better visibility, even in the long term.
Deburrs automatically.
Maximum shank grip in the chuck to ensure maximum torque transmission.
