SS SHOVAN 3PCS HSS Step Drill Bits 4-32mm

Key features

These SS SHOVAN step drill bits combine a spiral four flute geometry with a titanium coating and HSS 4341 steel to deliver smoother drilling and reduced swarf in thin materials. The set includes three multi-step cone cutters covering 4–12mm, 4–20mm and 4–32mm ranges, each with a 1/4" hex shank to reduce slipping in the chuck. For general workshop and DIY use this kit is practical for sheet metal, plastic, aluminium, copper, timber and mould steel.

Technical details

• Name: 3PCS HSS Spiral Step Drill Bit Sets
• Material: HSS 4341
• Coating: Titanium coated
• Size: 4-12mm, 4-20mm, 4-32mm

Why it makes sense

The four flute spiral profile helps eject chips more cleanly than single flute steps, which can cut down on clogging and produce neater holes. The 118° X type openings support faster cutting according to the manufacturer, and the hex shank offers better grip in cordless drills and impact drivers. Expect a versatile tool that performs several tasks, from enlarging holes to deburring and chamfering.

Best use cases

For workshop maintenance, light fabrication and home projects these bits are handy when you need multiple hole sizes without changing tools frequently. It’s a solid option if you value straightforward control over hole diameter and the convenience of three overlapping ranges in a compact canvas bag. It’s worth noting that while the titanium finish improves wear resistance it does not make the bits impervious to heavy duty industrial use, so allow for appropriate speeds and lubrication with harder metals.

The set comes with a canvas pouch for storage and transport, and it works with drill presses as well as handheld drills. SS SHOVAN 3PCS step drill bits provide a practical mix of durability and versatility for everyday metalworking and DIY jobs. 😊🔧.
