Featuring indexable carbide inserts with quick and precise indexing, combined with an optimized tool body design and advanced coatings, the GM16.1 delivers high cutting speeds, extended tool life, and excellent surface quality. Offering efficient and reliable solutions for internal slotting, hexagon forming, and spline machining, the GM16.1 is the ideal choice for improving slotting efficiency and quality.

Product Overview – An Innovative Choice for Efficient Slotting

Traditional slotting processes typically use solid high‑speed steel slotting tools, which suffer from limited cutting speeds, rapid tool wear, and frequent changeovers. The GM16.1 indexable high‑speed slotting tool employs indexable carbide insert technology to fundamentally address these challenges—inserts can be quickly indexed without replacing the entire tool body; carbide materials permit higher cutting speeds; and optimized edge geometries combined with coatings significantly extend tool life. Widely used in automotive parts, construction machinery, hydraulic components, mold making, and other slotting applications, this tool represents an innovative advancement in slotting technology.

Working Principle & Structural Features

Slotting is a machining process in which the tool performs reciprocating axial motion against the workpiece, progressively removing material to form internal slots, internal polygons, or internal splines. The GM16.1 is mounted on a lathe turret, machining center tool magazine, or high‑speed slotting machine spindle. The tool cuts on the downward stroke and retracts on the upward stroke to avoid interference, gradually machining the feature to final dimensions through continuous reciprocating motion.

Key structural features include:

• Indexable carbide inserts: Manufactured from premium ultra‑fine grain carbide with high hardness and excellent wear resistance; inserts can be indexed to present fresh cutting edges, maximizing cost‑effectiveness

• Precision locating system: Precision positioning between insert and tool body ensures high repeatability, eliminating the need for re‑alignment after indexing

• Optimized tool body design: Manufactured from high‑strength alloy steel with excellent rigidity and impact resistance for stability during high‑speed slotting

• Advanced coating technology: Inserts available with TiAlN, AlCrN, and other high‑performance coatings for enhanced heat and oxidation resistance in dry, wet, and high‑speed slotting conditions

Key Features & Benefits

1. High Efficiency – Significantly Boosting Productivity
The GM16.1, with carbide indexable inserts, permits higher cutting speeds and feed rates for high material removal rates. Cycle times are significantly reduced—particularly suitable for high‑volume slotting production.

2. Quick Insert Indexing – Minimizing Downtime
When an insert edge wears out, simply index the insert to a fresh cutting edge—no need to replace the entire tool. Changeover times are dramatically shortened, reducing machine downtime and improving utilization.

3. High Precision – Excellent Surface Quality
The precision locating system ensures consistent cutting position even after repeated indexing. The resulting longitudinal slots, internal hexagons, and internal splines feature accurate dimensions and smooth surfaces—meeting precision fit requirements.

4. Versatile – One Tool for Multiple Applications
The GM16.1 suits longitudinal slotting, internal hexagon forming, internal spline machining, and more. With different insert specifications, the same tool body handles various slotting operations—maximizing equipment utilization.

5. Extended Tool Life – Lower Overall Cost
The combination of carbide substrate and advanced coatings provides excellent wear resistance and impact toughness. With multiple cutting edges per insert, overall tooling cost is substantially lower than solid slotting tools.

Typical Applications

• Longitudinal slotting: Internal longitudinal slots in shaft sleeves, flanges, and housing components

• Internal hexagon forming: Hexagon socket holes and hex wrench interfaces

• Internal spline slotting: High‑efficiency internal spline tooth forming

• Hydraulic components: Internal slots and splines in valve bodies and pump housings

• Automotive parts: Internal feature slotting in transmission housings and steering gear housings
