Drill bit Smart HSS for metal 4.8 mm — pack of 10 (brand Smart, MPN 11-048)

Smart HSS drill bit for metal, 4.8 mm diameter, pack of 10 provides a set of straight-shank high-speed steel bits intended for drilling precise 4.8 mm holes in a variety of metals. The HSS construction is designed to retain hardness at elevated cutting temperatures, making these bits suitable for general metalworking, maintenance and repair, metal fabrication and do-it-yourself projects where accurate holes in ferrous and non-ferrous metals are required. The straight shank fits standard drill chucks for use with handheld and bench drills.

Advantages

High-speed steel material ensures wear resistance and cutting performance when drilling through steel and other metals. The consistent 4.8 mm diameter across the pack supports repeatable hole sizing for production or repair tasks. Straight shank design offers compatibility with common drill chucks and quick bit changes. Supplied as a pack of 10, the set reduces downtime from dulling or breakage by providing multiple ready-to-use replacements.

Suitable for

• Drilling holes in mild steel, stainless steel and non-ferrous metals
• Metal fabrication and assembly work
• Maintenance, repair and overhaul tasks
• DIY projects requiring precise 4.8 mm holes

Key specifications

• Material: high-speed steel (HSS)
• Diameter: 4.8 mm
• Shank type: straight shank
• Quantity: pack of 10 drill bits
• Compatible with: standard drill chucks (handheld and bench drills)

How to use

Select the 4.8 mm HSS bit from the pack and secure it in a clean, adequately tightened drill chuck. Use appropriate cutting fluid or lubrication when drilling tougher steels to reduce heat and extend bit life. Start at low speed to establish a pilot groove, then increase speed to a rate suitable for HSS bits and the metal being drilled. Apply steady, moderate feed pressure and clear swarf frequently to maintain cutting efficiency. Replace bits from the pack as they wear to preserve hole quality.

Usage recommendations

Wear appropriate eye and hand protection when drilling. Match drill speed and lubricant to the type of metal: lower speeds for stainless steel, higher speeds for softer non-ferrous metals. Clamp the workpiece securely and use cutting fluid on thicker or harder materials to prolong bit life and improve hole finish.
