Feature(may vary by option.)

●COBALT STEEL - Manufactured from solid M35 grade cobalt steel, with 5% cobalt added to create a hardened heat-resistant alloy, for much faster cutting and extra long life span.
●12 STEPS - The step bit comes with 12 sizes ranging from 4mm to 13mm, so you can drill up to 10 holes of different diameters with one bit, saving you time and efforts to change bits.
●FOR STAINLESS STEEL - Ideal for drilling new holes or and enlarging existing holes on stainless steel as well as softer metals like iron, brass, copper, aluminum, etc.
●GOOD PERFORMANCE - The dual-flute design provides greater speed and control along with jam-free performance. The fast-start no-walk tip allows you to drill without a center punch.
●1/4" HEX SHANK - Compared to bits with round shanks, this 1/4 " hex-shank step bit can be gripped more tightly by compatible drills and screwdrivers for greater torque.

Description

  • Cobalt step are not made of pure cobalt, but rather a steel alloy with certain percent cobalt. The 5-percent alloy is known as M35 grade.
  • The cobalt increases the strength of the steel and makes it more heat-resistant, making them an ideal cutter for stainless steel, as well as softer materials like cast iron, titanium and other hard or abrasive metals.
  • The 5% blended cobalt also gives the bit a much longer life – an important point considering that step bits are difficult to sharpen.
  • Possibly, this will also be one of the most expensive single bits you own. Just keep in mind that you cover multiple sizes with each bit.

The following tips may help you do a better job

  • Please use water or lubricant to keep the bit cool for longer tool life.
  • Fasten the workpiece securely to avoid shaking during drilling.
  • Drill with low RPM. Make sure to use an (RPM) adjustable drilling device.

Cobalt Steel Step Drill Bit

Excel at both making new holes and enlarging existing ones

Step drills are among the best drill bits for making holes in thin metal.

This step bit starts with a short pilot, then moves through a series of increasing widths as you move from one step to the next.

Its great for moving beyond your standard twist bit sizes and eliminating the need for a punch.

It also features a twist flute with a slight taper at each step. This gives you the ability to drill in sheet metal and other thin metals that might deform if you cut through at an angle.

  • Easily enlarges existing holes
  • Cobalt blend offers outstanding life
  • Multiple bit sizes on one accessory
  • Eliminate the need for a knockout punch on smaller holes

Hex Shank

Compared to bits with round shanks, this 1/4 " hex-shank step bit can be gripped more tightly by compatible drills and screwdrivers for greater torque.

Split Point

A split-pointed tip gets the hole started quickly and helps reduce the amount of wandering your bit does.

Laser Mark

It seems like a small thing at first, but we laser etches the measurements on the inside of the flute where they won’t wear off over time.

Please be ware of the length of the 1/4" hex shank

  • There are different standards of 1/4" hex shanks. Some customers found the shank of this product is too long to lock into their impact drivers.
  • The problem can be solved by making the shank shorter with a grinding wheel. You can also hold it with a standard 3-jaw drill chuck.
