EWE digital fine boring heads connect to BIG KAISER's user-friendly smartphone and tablet app, making it easier to monitor and configure the head while assembling and running boring tools. As well as being able to read changes in cutting diameter, the app helps operators determine optimal cutting parameters from their tool assemblies. The app also logs historical adjustments for all tools ever synced with it, providing essential information for companies adopting smart manufacturing.

Thanks to the large display on these digital boring heads, machining of extremely precise bores has become very easy. Moreover, the user friendly digital display shortens the time for adjusting the boring head by at least 20%. Thanks to intelligent electronics with automatic switch off function which, automatically stores the last displayed value, operator error can be drastically reduced.

The C-Centering Cutter is a multifunction cutter capable of both spot drilling and chamfering. The coolant hole allows cooling of the cutting edge, which reaches high temperatures during spot drilling in particular, and enables immediate chip evacuation.
During spot drilling, the insert nose radius can be easily chipped with general cutters since the center has a peripheral speed of zero. At the nose radius on the C-Centering Cutter insert forms negative land, it has high chipping resistance and the tool life is significantly extended.

Center Boy can achieve accurate centering and chamfering in a single operation. It features sharp cutting with minimum interference thanks to a slim and extended shank. The cutting tip is easily replaced to maintain high performance without need for re-grinding.

Series SW 319 twin cutter rough boring heads are designed for heavy duty rough boring and semi-finishing operations. The short and compact design of the components combined with a positive and friction locked connection between the tool body and insert holders provide maximum rigidity and highest cutting performance.

The BF-Cutter was exclusively designed for back spot facing of capped bolt holes, sizes M6-M16, or 1/4"-5/8. It features the world’s smallest square indexable insert, (with 4 indexes), and is ideal for all steels, (including stainless), cast iron and aluminum.
The coolant-through capability helps cool down the back side cutting area, increasing tool life – a feature not available in most other models on the market. The BF-Cutter is available for minimum facing diameters. A unique, offset design allows for easy programming – simply offset the centers between the machine spindle and the hole when entering or exiting the hole with the cutter.

The EWN single cutter boring tool program for finishing covers a range of Ø 20 - 203 mm with only 7 precision boring heads. Large work range due to 3 different insert holders for each boring head. Insert holder can be mounted in opposite direction for an easy changeover to back boring.

The EWN/EWD Smart Damper dampens vibrations and reduces chatter in deep-hole finish boring and extended-reach face milling applications – thus achieving better surface finishes and improved metal removal rates.

Designed exclusively for chamfering, the C-Cutter inserts have high rake angle to produce clean chamfer surfaces. The large cutting surface covers a wide range of diameters and reduces tooling numbers and ATC time loss.

C-Cutter Boy is designed to simplify your chamfering operations on manual bench drilling machines. Its Carbide support pads and Carbide inserts provide long tool life. 3 cutting edges make it an economical option.

R-Cutter is an ultra-high feed radius chamfer mill capable of front and back chamfering. It has a unique insert geometry offers excellent sharpness and its high rake angle reduces cutting resistance and minimizes the generation of burrs. There are indexable cutters with up to 4 cutting edges for fast, efficient production of radius edges.

Whether you're end milling, peck-drilling, helical milling, or shoulder milling, BIG KAISER offers high precision end mills that achieve smooth and quiet milling.
Our powerful indexable insert endmills offer excellent sharpness and toughness to achieve smooth, stable and heavy duty cutting comparable to that of solid endmills.
We offer a wide variety of shanks including BIG-PLUS® dual contact fit with an integral body.

Air driven high speed micro machining spindle speeders provide improved cycle times and finishes over conventional machine tool spindles. Our air power spindle for high speed micro machining with a Ø 1.5 mm (Ø.059") or smaller cutter operates at speeds of ≥40,000 RPM to 50,000 RPM.

Available as:

- Center Through Type - Compressed air through the machine spindle

The MEGA Synchro Tapping system is perfect for high performance rigid tapping on CNC machines. The system has 41 bodies, 45 tap holders, and offer ideal projection lengths for any machine. Thread quality and tool life is improved by reducing thrust loads caused by synchronization errors during rigid tapping.

Additionally, the Drill Tapper system provides high performance for manual applications and is a unique system for drilling and tapping. This quick-change holder lets you exchange taps and drills in seconds, providing two operations with one stable head.

The thick wall body and high gripping force of Hi-Power Milling Chucks ensure high rigidity and stable performance. Fine and narrow slits in the body make the clamping part deform properly to ensure even & strong gripping force and stable runout.

Hydraulic Chucks are ideal tool holders for machining processes that require high accuracy such as drills, reamers, ball mills, end mills, diamond reamers and grinding tools. With a wide variety of tool diameters and projections to fit any application, they are also available for simultaneous fit systems and all other major interfaces. Hydraulic Chucks are the perfect tool holder for high precision machining in automotive, aerospace, medical, and die & mold.

Universal AGU30 Type Angle Heads use a unique constant velocity joint to shed weight and allow for higher performance than other angle heads. The joint transmits enough torque to outperform traditional, spiral beveled gear 90° angle heads, while a low backlash design means better surface finishes with fine milling. The flange structure keeps rigidity at a constant despite the angle of the head, unlike a swing structure in which rigidity is dependent on the cutting direction. Also, because the mechanism is sealed, the AGU30 provides better coolant and chip proofing.

The spindle angle is adjustable from 0° - 30°, and is easily adjustable using the scale indication on the body. The cutter head is adjustable a full 360°.

AGU90 Type Angle Heads, with an adjustable spindle, (1° - 90°, 1° increments), combine vertical and horizontal operations on one machine. They increase productivity by easily changing the angle of the cutter while utilizing the original workpiece setup. This improves overall accuracy and eliminates the potential for error created by multiple setups. BIG-PLUS® is standard for all SK & BT versions, ensuring rigidity and accurate automatic tool changes.

SPERONI STP FUTURA is the standard by which all other tool presetters are measured. FUTURA is a high precision modular tool presetting system designed to increase profits and available machining time. All Speroni STP FUTURA models can achieve repeatable precision of 1 micron or better.

FUTURA is constructed with Pearlitic class 40 cast iron; this provides for added precision and consistency to measurements and increased system stability and durability. The first class quality and construction of Speroni tool presetters are complimented by a world class service and support team.

Leading manufacturers from all industries are taking advantage of the time-saving, accuracy enhancing benefits of tool presetters to make their companies more competitive in today's tight market.

Presetters measure the cutting edges of your tools to assure they precisely match job specifications and are ready to be used in the machine. Adjustments that could take up to 15 minutes when made on your machine can be made offline in less than a minute on a presetter, while your machine continues cutting.

Hydraulic chucks for Swiss lathe use a single wrench, which makes for an easy exchange of the cutting tool on the turret. High precision cutting by Hydraulic Chuck is achieved on the Automatic Lathe.

Your machine spindle spins the ChipFan blades to provide high volume air cleaning power. ChipFan provides a safer and faster method of removing chips and coolant from your tables, fixtures and workpieces than conventional air.

The ChipFan can be programmed into your machining cycle to help reduce downtime and make necessary cleaning a part of the work cycle.

With this innovative centering tool spindles and tools can be centered—ideal for limited spaces within small lathes.
