1. Material and Manufacturing Specifications

The modular boring heads and tooling components are made from case-hardening alloy steel, case-hardened and tempered to a minimum core strength of 880 N/mm², with surface hardness between Rc 57 and 60. Threads are ground for precision fit. Proper cleaning and lubrication before assembly are emphasized to ensure functionality and longevity.

Boring Bars and Tooling Components Overview

1. Boring Bars for RIGIBORE and MICROBORE Cartridges

Diameters from 22 mm to 181 mm, lengths 9–12 mm, featuring a 53º 8' angle and dial scale graduated at 0.01 mm radius for precise adjustment. Special rings available for angular positioning. Cartridges supplied on request.

2. Adapters for SANDVIK COROMANT Inserts

Diameters 80–250 mm, lengths 9–13 mm, facilitating use of standardized inserts to expand tooling versatility.

3. Micrometric Fine Boring Heads

For finishing, diameters 23–153 mm, lengths 9–14 mm, with high-precision radial adjustment screw graduated at 0.01 mm diameter. TORX screws clamp rhombic inserts. Special angular positioning rings available.

4. Double Cutter Boring Heads

Designed for roughing, offering increased rigidity via larger contact surfaces. Integrated coolant outlets and optional setting gauge for diameter pre-adjustment. Diameters 23–153 mm, lengths 9–15 mm. Special rings for angular positioning included.

5. Insert Holders for Double Cutter Heads

Available in 70° and 90° variants. The 70° holders maximize use of all four cutting edges of rhombic inserts, improving tool life and cutting efficiency, with rigid clamping and unobstructed chip flow.

6. Micrometric Fine Boring Heads (Small Diameter)

Diameters 3–53 mm, lengths 9–17 mm, designed for finishing with special angular positioning rings. Detailed tool and sleeve dimensions provided.

7. Weldon and Whistle-Notch Holders

8. Tapping Chucks and Quick-Change Tapping Chucks

Support taps M3 to M28 with axial compensation for compression and extension, plus a release mechanism preventing rotation unless spindle reverses, aiding precise tapping depth control, especially in blind holes. Quick-change versions compatible with BILZ adapters cover taps M3 to M30.

9. Toolholder Blanks

Diameters 14.5–90 mm, lengths up to 90 mm. Critical zones treated to withstand 700 N/mm²; rest hardened to Rc 57–60. Include centering point per DIN 332 Form-R.

10. Rings for Angular Positioning of Boring Heads

Special rings for diameters 14.5–90 mm allow precise angular corrections at 90° and 180° increments, improving tool alignment and machining accuracy.

Critical Information and Best Practices

• Use angular positioning rings for precise tool alignment and repeatability.
• Dial scales graduated at 0.01 mm enable fine diameter adjustments for high-precision boring.
• Double cutter heads enhance rigidity and productivity in roughing.
• 70° insert holders maximize rhombic insert cutting edge usage, extending tool life.
• Tapping chucks with axial compensation and release mechanisms facilitate accurate threading, especially in blind holes.
• Toolholder blanks are hardened and precisely centered for durability and accuracy.
