SKU CH-H1BP-XJ47D

  • 1/2 inch diameter drills standard holes
  • 18 inch overall length reaches deep work
  • Two-cutter design clears debris efficiently
  • Spline shank locks into rotary hammers securely
  • New condition ensures full cutting life

Product Identity

The ARTU 02026 is a spline-shank drill bit sized at one-half inch diameter and eighteen inches overall length. It is built for rotary-hammer users who need to bore deep holes in concrete, masonry or stone. The two-cutter tip geometry targets clean material removal in hard substrates.

Thermals Noise Power

Friction heat builds steadily during extended drilling in dense aggregate so periodic withdrawal helps control tip temperature. The tool produces typical rotary-hammer impact noise and vibration levels with no additional sound-dampening features noted. Power draw depends entirely on the hammer-drill motor driving the bit.

Build And Mounting

The spline shank locks into compatible rotary-hammer chucks for positive torque transfer and quick bit changes. Hardened steel body resists wear when drilling reinforced concrete. The eighteen-inch length allows deep through-holes without extensions. Buyers whose machines accept only SDS-plus or SDS-max shanks cannot use this bit.

Questions about this item

How do I install the spline shank on this 1/2" x 18" drill bit, and what step do people often miss?

Insert the spline shank fully into the rotary hammer chuck until it locks with an audible click; the step users miss is twisting the bit slightly while pushing to engage all splines before tightening.

What maintenance will this 2-cutter spline shank bit need over time?

Sharpen or replace the two cutting edges when they dull; clean concrete dust from the flutes after each hole to prevent binding and heat buildup.

What limit appears first when drilling deep holes continuously with this 18" bit?

Heat buildup at the tip and flute clogging limit sustained drilling; withdraw frequently to clear dust and let the carbide cool.
