Catalog - RE-AL - Precision Solid Reamers

SPEED for more number of reaming holes - with at least double tool life to TiN capacity

We serve normally HSS-E materials for Reamers, and because of the New Surface Hard Coating called SPEED Reamer (TiAlN coated) which giving us the tool life improvement, the reaming fine quality and productivity, so we focus on the SPEED Reamers. Please, check it on comparison test. To reach the very precise tolerance and superior surface finish holes, we recommend to use the patented Floating holder.

The most important SPEED characteristics
Surface hardness	3000HV
Resistance to oxidation	850 celcius
Friction coefficient	0.4
Coating thickness max	1.5 micron

This new SPEED presents high resistance and thermic stability, and subsequently the SPEED reamers are offering an efficient protection against thermal overcharge and wear.
SPEED, the new reaming technology as an alternative to carbide reamers.

The advantages for the users

Improved cutting speeds: SPEED average 30 - 40 m/min (compared to approximately 20 m/min for TiN reamers)
Increased tool life: SPEED at least twice the TiN capacity
Efficient application for wet and low rate lubrication
Reaming of a wide range materials (steel alloies, treated steels, cast-iron etc)

FLOATING HOLDER (patented)

The goal of this floating holder is to achieve precise alignment of the reamer to the prebored hole in vertical and horizontal working conditions by means keep the oscillation 0.2 - 0.5 mm for horizontal use and 3 mm for vertical use by turn the adjusting nuts preserved with 2 screws adjustment.
The reamer clamped by collets ESX 12 - 20 - 25 -32, holder designed without or with through coolant supply.

Construction advantages

Needle-bearings working on precision ground surface to guarantee a smooth floating movement parallel to the axis. This offers perfect working conditions for the floating holder in vertical and horizontal applications.
All its parts are hardened and ground to tolerances of +/- 0.0025 mm. Subsequently, the floating holder absorbs all forces resulting from torsion and pressure.
The floating holder can be applied on all types of machines (conventional and CNC) due to the availability of cylindrical, taper, ISO, VDI or Weldon shank.

The Advantages of floating holder

Precise movement parallel to the axis
No centre adjustment - the reamer centres itself
Very precise tolerances and superior surface finish
Increased tolerance conformity and greater tool life due to the regular distribution of cutting forces on all cutting edges
Greater economy due to lower downtime and higher production rates
