Self-guiding drill produces better
quality bores
A solid carbide high precision drill with four cutting edges performs cutting and guides the tool produce significantly higher performances and better quality bores.
Miller Giga Drill - The new solid carbide high precision drill with four cutting edges Cutting and guiding the tool in the machined bore are principal features of tools used for machining bores Solid drills typically have two blades which go to the centre and two guide chamfers along the secondary blade

Form milling cutters offer 30% time saving
Wear-resistant PCBN form milling cutters produce such high surface qualities that the time spent for final manual polishing can be reduced by 30 to 50%.
Tool clamping cartridges fit minimal lubrication
To put minimal lubrication quantity technology into practice, many institutes and research groups have dealt with specific questions and solutions, but a tool supplier claims to show the way.
The fact that this does not have to always be the case will be demonstrated by the new Miller Giga Drill.
A total of four blades and guide chamfers allow this drill to produce significantly higher performances and better quality bores.
The increase in performance can be put to good use both in drilling and gun boring.
Two drilling and two gun boring blades cut the material.
The arrangement of the blades and the appropriate radial land allow machining values, for example when drilling in aluminium, of 200m/min and feeds of 0.8mm/rev.
For this four guide chamfers produce surface qualities in the area of Rz 4 micron, concentricity of <4 micron and a high dimensional stability.
The guide chamfers also have a positive effect when machining interrupted bores.
Of course this new drill also demonstrates its efficiency in steel and cast iron materials.
Miller also provides the special MxF coating with this new series.
This coating has already proved successful with the Mega and Quadro drills.
The Giga Drill is equally suited to wet machining and machining with minimal quantity lubrication.
The standard program includes series with 5xD or 8xD.
This new drill technology is also used in the area of special tools - for Giga Drills there are clearly no limits.
