Boring & Facing

Company Overview

D’ANDREA is an Italian company, world leader in the manufacture of high precision machine tool accessories. Known worldwide for the quality of its products, D’ANDREA has been developing increasingly effective technologies since 1951, keeping pace with the modern demands of the precision engineering industry.

The entire D’ANDREA range comes from its headquarters in Lainate, just outside Milan: TA-CENTER, TA-TRONIC, U-TRONIC, U-COMAX and AUTORADIAL facing and boring heads. The high precision modular tool holder system MODULHARD’ANDREA and the complete balanceable toolholder system for high-speed applications TOPRUN, MONOd', MONOforce and MCD'.

Modular Boring System


Arbor Extension Reduction

Arbor sizes MHD’ 80, 110 and 140 are recommended for heavy milling operations and for bores deeper than 250 mm and exceeding 125 mm in diameter


Carbide Bar

Carbide bars for deep-hole machining. D’Andrea solves the deep-hole boring machining by means of a wide program of BMD carbide bars having diameter 16, 20, 25, 32 mm diameter and ending with MHD’ arbor.


Chucking Tools

The complete program of D’Andrea modular adapters with MHD connection, satisfies the various processing needs related to milling, drilling, and tapping.


Double Bit Heads

The double-bit heads are easy and extremely rigid thanks to the extensive serrated areas in contact between the bit holder seats and the heads, together with the constant distance between the seat clamping screw and the cutter.


Double Bit Boring Crossbar

The BPS double-bit crossbars cover a working area from ø 200 - 2800 mm. The BPS double-bit crossbars are constructed in aluminum and mounted on a steel double-bit plate.


TRD: Combination Boring Head

The double-bit TRD heads allow both roughing and high precision finish thanks to their rigidity and the sensitivity of the sliding mechanism which can achieve radial correction of 5 microns. This can be carried out directly on the machine and easily read on the vernier scale. Diameter: Max.: 120 mm | Min.: 28 mm


TRC Heads (L.C: 10 micron)

High precision work to IT6 tolerance, with excellent surface finish, is achieved using TRC boring heads. These are very sensitive and radial correction of 10 microns can be effected directly on the machine and easily read on the vernier scale.


TRM Heads (L.C: 2 micron)

The TRM heads in the D’Andrea Testarossa line have a protective rustproof coating. High precision work to IT6 tolerance, with excellent surface finish, is achieved using TRM boring heads. These are very sensitive and radial correction of 1 micron can be effected directly on the machine and easily read on the vernier scale.


TR Elettra (Digital) Heads

The TR-Elettra is a finishing head, where the radial displacement of the tool holder slide is viewed on a built-in digital display, providing the operator with maximum speed and accuracy of adjustment. The operating range of these heads is extensive: from 2.5 mm to 2,700 mm depending on the size of the head selected.


Boring Kits

The Testarossa kits are supplied in a box with a wide range of tool holders, tools, inserts and service spanners.
