Drill Bit Set Silver 29 pcs titanium-coated HSS 1.5–27 mm model 10424

Silver drill bit set model 10424 comprises 29 titanium-coated HSS drill bits with sizes from 1.5 mm to 27 mm. The set is designed for metal drilling and provides a wide size range for workshop, repair and construction tasks. Titanium coating improves surface hardness and heat tolerance, making the bits suitable for extended cutting life and repeated drilling operations in steel and non-ferrous metals.

Advantages

The titanium-coated high-speed steel construction offers increased wear resistance and improved performance at elevated temperatures compared with uncoated HSS. A comprehensive size range from 1.5 mm to 27 mm reduces the need to change tools frequently and supports precise hole sizing. The set’s uniform geometry and coating help maintain cutting efficiency and reduce bit dulling during sustained use.

Suitable for

• Drilling holes in steel and stainless steel (depending on hardness)
• Work on non-ferrous metals such as aluminum and brass
• General metalworking in workshops and maintenance tasks
• Construction site drilling where a wide range of sizes is required

Key specifications

• Material: high-speed steel (HSS) with titanium coating
• Number of pieces: 29
• Size range: 1.5 mm to 27 mm
• Coating: titanium for increased wear resistance and heat tolerance
• Typical applications: metal drilling, repair and construction tasks

How to use

Select the drill bit size appropriate for the hole diameter required and secure it in a compatible drill chuck. Use moderate feed pressure and maintain recommended speeds for HSS bits when drilling metals; reduce speed for harder materials and increase coolant or lubrication to manage heat. Keep the drill perpendicular to the workpiece for accurate holes and withdraw periodically to clear chips and avoid clogging. Inspect bits for wear and replace when cutting performance degrades.

Usage recommendations

For best results when drilling metals, use cutting fluid or suitable lubricant to reduce friction and heat. Match drill speed to material hardness—lower RPM for harder steels—and allow the bit to cool between prolonged drilling cycles. Store the bits in their case to protect the titanium coating and maintain dimensional accuracy.
