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.

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.

Drill bits with 1/4˝ hex shank optimised for impact drivers.

Titanium nitride coating helps cool the drill bit and allows it to be used even at high speeds

The 135° point geometry reduces drill bit slipping and allows maximum drilling precision, without overheating.

Variable design flute. This allows faster material ejection and reduces accumulated heat, all for greater efficiency.

Sturdier design for greater durability and drill bit service life

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.

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.

MILWAUKEE® HSS-G Co drill bits combine high-speed steel and cobalt for superior precision, longer life and heat resistance. These high-performance drill bits are designed for fabrication, production and machining applications on hard metals and in conditions of heavy heat generation. Add a premium drill bit with precision sharpening to your kit with MILWAUKEE®. Choose from HSS-G Co drill bits in different diameters and lengths to suit your needs. The addition of cobalt makes these drill bits even harder and more heat-resistant than standard HSS drill bits. For greater versatility, MILWAUKEE® offers multi-size sets complete with sturdy cases to organise and carry your tools conveniently. Each HSS-G Co drill bit is made from high-speed steel alloyed with 5% cobalt and complies with DIN 338, ensuring quality and reliability for your investment. Use them to drill high-alloy steels and metals with a tensile strength above 1000 N/mm², smoothly and efficiently. The special QUAD EDGE™ point allows quick, precise starting, with a split 135° angle that eliminates slipping. The variable flute geometry ejects material more quickly, reducing the risk of tool overheating. The reinforced core, wider towards the shank, provides extra strength and less need for replacement

Tungsten carbide (TCT) cutting edge allows drilling into concrete, aerated concrete, bricks, slate and granite.

From Ø 5 mm the drill bits have a three-flat shank to prevent slipping in the chuck.

For Ø 3 & 4 mm the drill bits have a round shank.

The red flute makes identification easier for the user.

They can be used with rotary hammers, using the keyless chuck and selecting rotation mode.

Staples for M18 FFUS. Compatible only with the Milwaukee tool.

For all types of fences made of wood, e.g. livestock fencing, square mesh/chain-link/barbed wire and high-tensile wire.

Hot-dip galvanised coating for superior corrosion resistance.

4 mm thickness for the best durability in outdoor applications.

Sharp, divergent points: the staple point twists as it is driven into the wood, offering a better hold.

Red adhesive coating for improved drivability while maximising holding force.

Collated with paper tape.
