Hilti Hollow Drill Bit
Hilti Hollow Drill Bit in use with vacuum
Dust is removed by the vacuum while drilling is in progress for faster drilling, longer bit life and a virtually dustless working environment.
Hilti HIT-Z zero-cleaning rod
Cone-shaped helix works as a torque-controlled anchor and requires no hole cleaning when used with HIT-HY 200 adhesive.

Hilti's HIT-HY 200 Adhesive Anchor System eliminates the danger of inadequately-cleaned anchor holes reduce the performance of conventional adhesive anchor systems. Hilti Safe Set Technology requires no manual hole cleaning to obtain optimum performance.
New TE-CD and TE-YD Hollow Drill Bits used in conjunction with a vacuum clean themselves. Dust is removed by the vacuum while drilling is in progress for faster drilling, longer bit life and a virtually dustless working environment. This new anchoring method is only allowed with Hilti HIT-HY 200 adhesive.
The new Hilti HIT-Z, zero-cleaning rod, with its cone-shaped helix, works as a torque-controlled anchor and requires no hole cleaning. When used with HIT-HY 200 adhesive, the unique shape of the HIT-Z Anchor Rod allows it to be installed in a standard (hammer drilled, dry or water saturated concrete, above 41 deg F), uncleaned hole.
The current industry standard installation method uses compressed air and a wire brush to clean the drill hole. Like all Hilti adhesive anchors, HIT-HY 200 can be installed using the traditional blow-brush-blow method. Because HIT–HY 200 only requires two blows of compressed air, two brushes and two more blows of compressed air (2x2x2), it is faster to install than other adhesives on the market that require at least a 4x4x4.
Available in two versions with the same load performance: HIT-HY 200-R for “regular” working times and HIT-HY 200-A for “accelerated” working times allows contractors to choose the right adhesive for the application.
Hilti HIT-HY 200 Adhesive Anchor System and Safe Set Technology is pending ICC-ES approval for use in all seismic zones and uncracked and cracked concrete.
