Setting instruction
Review the Material Safety Data Sheet (MSDS) before use for proper
and safe handling!
Wear well-fitting protective goggles and protective gloves when
working with Hilti HIT-RE 100.
Important: Observe the installation instruction of the manufacturer
provided with each foil pack.
Drilling
Note: Before drilling, remove carbonized concrete; clean contact
areas (see Annex B1)
In case of aborted drill hole the drill hole shall be filled with mortar.
Drill the hole to the required embedment depth using a hammer-drill
with carbid drill bit set in rotation hammer mode, a compressed air
drill or a diamond core machine.
Hammer drill (HD)
Compressed air drill
(CA)
Diamond core wet
(DD) and dry (PCC)
Spacing applications
Measure and control concrete cover
cdrill = c + d0/2
Drill parallel to edge and to existing rebar
Where applicable use Hilti drilling aid HIT-HB
Drilling aid
Fore holes lv> 20 cm use drilling aid
Ensure that the drill hole is parallel to the existing rebar.
Three different options can be considered:
Hilti drilling aid HIT-BH
Lath or spirit level
Visual check

Drill hole cleaning
The drill hole must be free of dust, debris, water, ice, oil, grease and other
contaminants prior to mortar injection.
Just before setting the bar, the drill hole must be free of dust and debris
by one of two cleaning methods described below.
Inadequate hole cleaning = poor load values.
Manual Cleaning (MC) For drill hole diameters d0≤ 20mm and drill hole depths h0≤ 10·d.
Blow at least 4 times from the back of the drill hole until return air
stream is free of noticeable dust.
Brush 4 times with the specified brush by inserting the steel brush
Hilti HIT-RB to the back of the hole (if needed with extension) in a
twisting motion and removing it.
The brush shall produce natural resistance as it enters the drill hole
(brush Ø ≥ drill hole Ø) - If this is not the case, please use a new
brush or a brush with a larger diameter.
Blow at least 4 times from the back of the drill hole until return air
stream is free of noticeable dust.
Compressed air cleaning (CAC) For all drill hole diameters d0and all drill hole depths h0≤ 20· d
Blow 2 times from the back of the hole (if needed with nozzle
extension) over the whole length with oil-free compressed air (min. 6
bar at 6 m³/h)until return air stream is free of noticeable dust.
Brush 2 times with the specified brush by inserting the steel brush
Hilti HIT-RB to the back of the hole (if needed with extension) in a
twisting motion and removing it.
The brush shall produce natural resistance as it enters the drill hole
(brush Ø ≥drill hole Ø) - If this is not the case, please use a new
brush or a brush with a larger diameter.
Blow 2 times again with compressed air until return air stream is free
of noticeable dust.
If required use additional accessories and extensions for air nozzle
and brush to reach back of hole.
Compressed air cleaning (CAC) For all drill holes deeper than 250 mm (for ϕ8 to ϕ12) or deeper than 20·ϕ
(for ϕ > 12 mm)
Use the appropriate air nozzle Hilti HIT-DL.
Blow two times from the back of the hole over the hole length with oil-
free compressed air until return air stream is free of noticeable dust.
Safety tip:
Do not inhale concrete dust.
Use of the dust collector Hilti HIT-DRS is recommended.

Screw the round steel brush HIT-RB in one end of the brush
extension HIT-RBS, so that the overall length of the brush is
sufficient to reach the base of the drill hole. Attach the other end of
the extension to the TE-C/TE-Y chuck.
Safety tip:
Start machine brushing operation slowly
Start brushing operation once the brush is inserted in the borehole.
Use the appropriate air nozzle Hilti HIT-DL.
Blow two times from back of the hole over the hole length with oil-
free compressed air until return air stream is free of noticeable dust.
Safety tip:
Do not inhale the concrete dust.
Use of the dust collector Hilti HIT-DRS is recommended.
In addition for wet diamond corind (DD) For all drill hole diameters d0and all drill hole depths h0
Flush 2 times by inserting a water hose (water-line-pressure) to the
back of the hole until water runs clear.
Brush 2 times with the specified brush by inserting the steel brush
Hilti HIT-RB to the back of the hole (if needed with extension) in a
twisting motion and removing it.
The brush must produce natural resistance as it enters the drill hole
(brush Ø ≥ drill hole Ø). If this is not the case, please use a new
brush or a brush with a larger diameter.
Flush 2 times by inserting a water hose (water-line pressure) to the
back of the hole until water runs clear.
Rebar preparation
Before use, make sure the rebar is dry and free of oil or other
residue.
Mark the embedment depth on the rebar. (e.g. with tapte) , v
Insert rebar in borehole, to verify hole and setting depth v.
