Products Description
The Brazed Boring Bar features a strong, permanently bonded cutting tip for stable internal machining. It offers high rigidity, good wear resistance, and cost-effective performance for boring operations.
This Rough Boring Head uses cemented carbide brazed tool bits. The brazing is solid, the edge stays sharp, and the hardness holds up. You can bore steel, cast iron, whatever you're working with. Even after months of daily use, you won't see the chipping and wear you get with cheaper setups.
The tool holder body is high-carbon steel, heat-treated and quenched. It's hard, it's tough, and it's rigid. When you're taking heavy cuts, this holder suppresses the chatter that ruins surface finish and dimensional accuracy. Machining stays stable even when you're pushing the limits.

This is a multi-size set. Different holders for different bore diameters, all designed to work with F1 Type Boring Head setups. You can go from rough boring to finish boring without changing your whole setup. One set covers the range of jobs you'll see in a typical shop.
Straight shank design means it clamps directly into F1 boring heads, milling machines, drilling machines-whatever you've got. The positioning is accurate, installation is straightforward, and you spend less time dealing with clamping errors. That translates to better efficiency and fewer scrapped parts.

Wide machining range. Internal boring, reaming, chamfering-it handles all of it. Mold work, mechanical repair, hardware processing, this Indexable Boring Head setup works for single-piece repairs or full batch production. It's the kind of versatility you need when every job is different.
Comes with a wooden storage stand. Tool holders insert by size and type, so they're not banging around in a drawer getting damaged. You can identify sizes at a glance, grab what you need, and keep the workshop organized. Less time hunting for tools, less money lost to damaged equipment.
The real value here is cost-effectiveness. Brazed tool holders cost less upfront and they're easy to maintain. When the tool bit finally wears down, you don't scrap the whole holder-you re-braze it or replace just the bit. This Rough Boring Cutter approach cuts your long-term machining costs significantly. For boring operations, it's hard to beat this level of value.
