Big Kaiser Celebrates 70 Years
It has been 70 years since Mr. Kaiser started his success story with strong will, much faith and a little bit of luck. Many things have changed in the world of manufacturing and technology, but the quality standards of Big Kaiser Precision Tooling are unchanged, the company says.

Clamping system

Uniflex Clamping System Designed to Hold Uneven Parts
Big Kaiser’s Uniflex 3D zero-point clamping system provides vibration-free holding of the part when multiple clamping is used and has low-wear against tools.

Chamfering tool

Modular Round Chamfering Tool Cuts in Tight Spaces
Big Kaiser’s R-Cutter CKB type is a modular round chamfering tool that offers an insert geometry that is said to provide extreme sharpness.


HDC Straight Shank Toolholder Handles Clearance Applications
Big Kaiser’s HDC Straight Shank holder has a slim design that provides balance, concentricity and reach for confined areas and can be clamped into other base holders to extend overall reach of the tool assembly and avoid the need for special tools. 

Hydraulic chuck

Chuck Clamps Ultra-Small End Mills without Reduction Sleeve
Big Kaiser’s super slim type of hydraulic chucks (HDC) for HSK-E25 machine spindles are toolholders that can clamp ultra-small end mills and drills directly, without needing a reduction sleeve.

Rough boring heads

SW Smart Damper Rough Boring Heads Absorb Vibration
Big Kaiser’s SW Smart Damper rough boring heads with CKB modular connection system’s damping capability minimizes the effects of high frequency oscillations, absorbing vibration effectively and allowing higher machining accuracy.

Mega New Baby Chuck 25N

Mega New Baby Chuck 25N is Designed for High-Speed Cutting
Big Kaiser’s Mega New Baby Chuck 25N is available up to a diameter of 1" clamping for drills, reamers and finishing end mills with .00004" runout accuracy, is designed for high-speed cutting and guarantees a 1 micron runout at the collet nose. 

Mega ER Grip

Mega ER Grip Designed to Outperform Standard ER Systems
Big Kaiser’s Mega ER Grip was designed to outperform all standard ER systems in the four most critical areas of tool holder performance: clamping force, concentricity, rigidity and balance at high spindle speeds.

Big Kaiser Donates to National Robotics League
The donation was the result of a year-end promotion by Big Kaiser, giving back to the association a percentage of every order by an NTMA member company.

Big Kaiser Smart Damper boring bar

Smart Boring Bar for Lathes
A heavyweight, strengthened damping mechanism integrated into the toolholder functions as both a dynamic counter and friction damper.

Indiana High School’s Precision Machining Program Receives Donation
The Speroni Magis tool presetting and measuring system was donated to the program after it was replaced with newer equipment at Andretti Autosport in Indianapolis.

Indiana High School’s Precision Machining Program Receives One-of-a-Kind Donation
Big Kaiser Precision Tooling recently donated an Andretti-Autosport-branded tool management system to the Precision Machining program at Plymouth Community Schools.

Big Kaiser’s Smart Damper Designed for Turning
It instantaneously absorbs vibration and eliminates chatter, helping to achieve higher machining accuracy, better surface finishes and increased metal removal rates for higher productivity at critical machining depths.

Live Demo Video: New Digital Boring Head and App
The EWD EVO digital boring head from Big Kaiser connects with newly developed smartphone and tablet app.

Deep Hole Drilling

Tools and Technologies for Deep Hole Drilling
Understanding the challenges and knowing how to select and apply the appropriate tools will help a shop profit from this difficult operation.

New Micro Engraving Tools Available from Big Kaiser
The solid carbide engraving cutters are designed to provide sharp, positive cutting geometry, resulting in burr-free surface finishes and smooth transitions.

Big Kaiser Face Grooving System for Twin-Cutter Boring Heads
The face grooving system can be used as either a single or twin cutter grooving tool for diameter ranges from 2.087” to 118” diameter. The design allows for a grooving depth of as much as 0.472”, with a minimum width of 0.079” and a maximum of 0.375”.

Protecting Against Tooling Pullout
When milling heat-resistant super alloys, tool pullout is a familiar occurrence. This heavy duty milling chuck helps keep your tooling in place and your machine in motion.
