HT7 Disc Floor Sander
The HT7 is a high performance disc floor sander (edger)
that delivers unrivalled balance and feel. The choice of professionals, the HT7
delivers the power to tackle the toughest of jobs. Designed to be easy to
handle, with bias off switching and optional disposable paper dust bags for safe
and simple operation, whatever the job
Features
The HT7 has been precision engineered to meet the
challenging demands of the tool hire and rental, contractor and professional
markets. The powerful four brush motor drives a dynamically balanced sanding
pad. The HT7's drive is transmitted through a hardened steel alloy pinion and
large diameter aluminum bronze drive gear that will not slip or stall. Motor
commutation is via Hiretech's precision molded brush block and brass brush
holders. Constant force brush springs ensure a smooth, consistent power
transmission.
Hiretech's unique metal backed sanding pad gives the HT7
the balance, feel and touch demanded by the professional craftsman. A high
precision press tool produces a dynamically balanced disc to which the rubber
sanding pad is bonded using a specially developed process. This special process
allows the rubber pad to be bonded to the metal back leaving an 8mm (5/16") deep
rubber edge around the whole circumference of the disc. This design also allows
the pad to be accurately trimmed and properly maintained throughout its life.
Operator safety is improved as the soft edge reduces the risk of base boards,
pipe work and other exposed work surfaces being cut into.
Manufactured as a dynamically balanced component, the
HT7 sanding pad does not require any additional balancing or corrective
procedures to make it run without vibration. This ensures that the HT7 will run
smoothly - prolonging the life of the pad, drive gear and motor.
The HT7 Disc Floor Sander will sand a high quality,
score-free finish on hard and soft wood floors, including parquet and any solid
wood surface that requires rapid sanding and leveling. The HT7 can also be used
on a wide range of other surfaces including some types of decking, fiber board,
cork and composition floors. Ideal for confined areas such as closets, stair
treads and sanding right up to the edge of a floor (edge sanding), without
damage to the base board or skirting.
The bias off switch and optional disposable paper dust
bag system makes the HT7 the safest disc floor sander available. The continuous
heavy duty self-cooling four brush motor will not stall or slow down under load
when sanding with coarse grit abrasives, removing old surface finishes and
deposits of wax and dirt. The HT7’s superb balance and feel make it easy to sand
a score-free finish, with a high production rate and fast stock removal when
needed
Key Design Features
- Biased off switch with power connected indicator
light, prevents the HT7 from accidental start-up protecting operator and
property.
- Precision molded brush block with brass brush
holders and constant force brush springs.
- Optional disposable paper bags for efficient and
safe dust collection. Manufactured from recycled materials, Hiretech
disposable paper dust bags are the environmentally friendly way to handle
and dispose of the dust created during the sanding process.
- Economic handle design minimizes fatigue when
used over extended periods of time. Handles securely support the HT7 in an
upside-down position for easy changing of abrasive discs.
- Dust bag support folds upright to provide cable
storage. 7m (23') power cable with non-marking outer insulation prevents
marking of newly sanded floor.
- Wheel castors allow HT7 to glide effortlessly
across floor surface allowing easy changes in direction.
- Storage for sanding pad wrench.
- High powered vacuum system, with seated oversize
wide bladed alloy vacuum fan.
- Hardened steel alloy pinion and large diameter
aluminum bronze drive gear that will not slip or stall.
- Hiretech's unique dynamically balanced metal
backed sanding pad provides superb feel and touch and consistent sanding
performance on all floor types and conditions.
- ABS disc guard freely rotates against base
boards and skirting preventing damage and protects the sanding pad.
- Polished aluminum alloy body
