## Summary description

Multistep drill bit HOGERT HT6D321 with a 4–12 mm step range designed for drilling sheet metal and thin materials. The multistep profile allows drilling multiple hole diameters with a single bit, reducing tool changes. Suitable for workshop and field use on hand drills or drill presses; provides efficient hole enlargement and deburring in one operation.

## Long description

Multistep drill bit HOGERT HT6D321 — 4–12 mm step range, multistep design is a single cutting tool engineered for drilling and enlarging holes in sheet metal and other thin materials. The stepped geometry integrates multiple diameters along one flute, allowing consecutive hole sizes from 4 mm up to 12 mm without changing bits. The tool is compatible with handheld drills and drill presses commonly used in workshops and on-site applications and performs cutting and light deburring in a single pass.
Advantages
The multistep profile reduces the need for multiple individual drill bits, saving setup time and minimizing tool changes. A single-spiral flute and stepped cutting edges provide progressive material removal and stable centring on thin metal sheets. Its consolidated design enables faster hole enlargement and combined deburring compared with separate drilling and finishing operations. The bit is suitable for both intermittent field work and repetitive workshop tasks, offering predictable hole sizes across the 4–12 mm range.
Suitable for
Drilling and enlarging holes in sheet metal, thin steel and aluminium panels
On-site maintenance and repair tasks requiring multiple hole sizes
Workshop use with hand drills and drill presses for rapid hole size changes
Applications where combined drilling and light deburring in a single pass improves efficiency
Key specifications
Step range: 4 mm to 12 mm (progressive stepped diameters)
Design: multistep/stepped drill geometry with single cutting flute profile
Typical material application: sheet metal, thin steel, aluminium and similar thin materials
Compatible tools: handheld electric drills and drill presses with standard chucks
Primary function: drilling, hole enlargement and light deburring in one operation
How to use
Secure the workpiece to prevent movement and ensure a flat, supported surface to reduce vibration. Mount the multistep bit in the drill chuck and tighten securely. Start drilling at low to moderate speed suitable for thin metals, applying steady pressure while allowing the stepped profile to cut progressively through material. For best hole quality, back off occasionally to clear chips. After reaching the desired step, withdraw the bit slowly while maintaining rotation to help remove burrs. Use appropriate coolant or cutting fluid when drilling tougher alloys or during prolonged drilling to extend bit life.
Usage recommendations
Use center punching or a pilot hole for improved guidance when positioning holes in very thin or flexible materials. Match drill speed and feed to material thickness: higher speeds for softer metals like aluminium, lower speeds for harder steels. Inspect the stepped cutting edges regularly and replace the bit if wear affects hole size precision or increases burr formation.
