Shipping in 3-5 business days from Krollit warehouse for spare parts and accessories. Customer support in Italian available for technical documentation and compatibility verification with the reference machine. Krollit has been an official distributor since 2007.
Who is the 155 mm drilling machine vise for?
The 155 mm drilling machine vise is recommended for the following professional profiles:
-
Mechanical workshops and millers: secure clamping of workpieces during milling and drilling on machine tools.
-
Production departments with serial processing: rapid and repeatable clamping for production cycles.
Not suitable for: turning cylindrical workpieces (lathes require self-centering chucks, not milling machine vises).
Frequently Asked Questions
What is a drilling machine vise used for?
The 155 mm None vise is sized for drill presses and drilling machines, with reduced weight and T-slots for quick attachment to the table.
Drilling machine vises are lighter than milling machine vises (less rigidity in the guides, but sufficient for the lower torque of drilling). The None series is specific for intensive use.
What does the 155 mm dimension indicate?
It indicates the jaw width (155 mm). The clamping width is generally equal to or slightly greater than the jaw width.
To choose the size: as a rule of thumb, the jaw width should be at least 70% of the size of the workpiece. For workpieces >100 mm, choose 155 mm vises or larger.
Which machine is it mounted on?
It is mounted on drill presses and bench drilling machines with a standard table.
Check for the availability of T-slots on the drill table. Milling machines require precision vises (PS, KV, PHV), not drilling machine vises.
Are the jaws replaceable?
Yes, the jaws are hardened, ground, and fully replaceable. This is an important advantage for long-term maintenance.
The jaws are the wear point of the vise: after thousands of clamps, they may show indentations or deformations. Replacement is autonomous with the dedicated fixing screws. Krollit supplies original replacement jaws.
How is precision maintained?
Regular cleaning of the guides and jaws, application of a light coat of oil to the sliding parts every 50 hours of use, periodic checking of parallelism with a dial indicator.
Chips accumulated in the guides compromise parallelism precision. For intensive use with coolant, dry the vise at the end of the shift to prevent rust on the ground parts. Acceptable parallelism tolerance: 0.02-0.05 mm over the length.
