Drill Bit Set Smart365 HSS short bits 22 mm, 24 mm, 25 mm (3 pcs)

Short HSS drill bit set Smart365 HSS short bits 22 mm, 24 mm, 25 mm (3 pcs) contains three high-speed steel drill bits sized 22 mm, 24 mm and 25 mm. These short-format bits are intended for drilling metal, plastic and wood where a reduced flute length improves rigidity and control. The set is suitable for use with handheld drills and drill presses in workshop, maintenance and installation tasks that require stable, straight drilling and reduced wandering.

Advantages

The Smart365 short HSS bits provide increased stiffness compared with standard-length equivalents, which reduces chatter and helps maintain drilling accuracy in thicker or harder materials. Being made of high-speed steel, the bits retain hardness at elevated cutting temperatures and are compatible with common lubricants and cutting fluids. The set covers three commonly used large diameters, reducing the need to purchase single bits for occasional large-hole work.

Suitable for

• Drilling holes in mild steel, aluminium and non-ferrous metals
• Drilling plastic components where controlled entry and exit are needed
• Making holes in wood and plywood where reduced bit flex is beneficial
• Handheld drilling and drill press operations in workshops and maintenance

When it may not be suitable

The set may not be the best choice for precision reaming or countersinking operations that require specialized geometry or longer reach. It is also not intended for use on hardened steels, stainless steels with high alloy content, masonry, or concrete; for those materials select purpose-designed masonry or carbide bits.

Key specifications

• Material: high-speed steel (HSS)
• Bit lengths: short flute design for improved rigidity
• Diameters included: 22 mm, 24 mm, 25 mm
• Intended materials: metal, plastic, wood
• Compatibility: handheld drills and drill presses

How to use

Select a suitable drill speed and, when drilling metal, apply cutting fluid to reduce heat and extend tool life. Secure the workpiece to prevent movement and center-punch metal surfaces where precise positioning is required. Clamp the bit in the drill chuck ensuring proper alignment and run the drill at steady feed pressure—avoid excessive force that can break the bit or cause chatter. For deep holes stop periodically to clear chips, and finish with deburring as necessary.

What to consider before purchase

• Confirm the diameters (22 mm, 24 mm, 25 mm) match the hole sizes required for your project
• Evaluate whether short flute length provides sufficient reach for your intended application
• Consider material compatibility—HSS is suitable for common metals, plastics and wood but not for masonry or hardened alloys

Usage recommendations

Use moderate speeds and cutting fluid for metal drilling, secure workpieces firmly, and keep feed pressure steady to maximize bit life and hole quality. Replace bits that show wear or chipping to maintain drilling accuracy and safety.
