Discover Summit HTM4H‑S: The Ultimate Horizontal Boring Mill for Heavy‑Duty Applications

Summit is committed to delivering cutting-edge machine tools to many of the world’s largest manufacturers and machine shops. Our HTM series of horizontal boring mills are trusted by engineers and craftsmen in need of boring mill solutions for heavy-duty applications.

What Are Horizontal Boring Mills?

Boring mill machines are used to enlarge holes in many different types of materials by using a single-point cutting tool. There are two variations of boring mill machines on the market:

• Horizontal boring mills enable the workpiece to rest on the machine’s table while the boring bar rotates around a horizontal axis.
• Vertical boring mills make the workpiece rotate around a vertical axis while the boring tool moves without turning.

Simply put, a horizontal mill’s workpiece is stationary while the tool turns and a vertical mill’s workpiece turns while the tool is stationary.

Do horizontal boring mills offer high precision?

If you’re looking for a horizontal boring mill with the precision to fuel productivity and establish a competitive edge, you should explore our HTM series. These heavy-duty machine tools are perfect for large workpieces and offer more versatility than other solutions on the market.

Why do you need a horizontal boring mill?
