Drill bit set Irwin 10502569 — 19 pcs, HSS, for drilling

Irwin 10502569 is a 19-piece drill bit set manufactured from high-speed steel (HSS) for general-purpose drilling. The set includes a range of commonly used diameters suitable for metal and wood, presented in a compact case that is convenient for storage and transport. Designed for workshop, construction and DIY environments, these HSS bits provide a balance of cutting performance and wear resistance for routine drilling tasks.

Advantages

The HSS material offers improved heat resistance and hardness compared with standard carbon-steel bits, which helps maintain edge retention during repetitive drilling. The 19-piece range covers multiple diameters so you can select the right size without stopping to regrind or change tools frequently. The compact kit keeps bits organized and reduces the risk of losing individual drills on site or in a toolbox.

Suitable for

• Drilling holes in mild and alloy steels
• Drilling through wood and timber elements
• General workshop repair and maintenance
• Construction and on-site drilling tasks
• Home DIY and furniture assembly

Key specifications

• Number of pieces: 19
• Material: high-speed steel (HSS)
• Application: general-purpose drilling in metal and wood
• Kit weight: approximately 550 g
• Storage: compact carrying case for organization

How to use

Select the correct drill diameter for the hole required and secure the workpiece to prevent movement. Fit the chosen HSS bit into a compatible drill chuck and tighten securely. Start drilling at low speed to establish a pilot, then increase speed and apply steady, moderate pressure. For metal drilling, use appropriate cutting fluid to reduce heat and extend bit life. Withdraw the bit periodically to clear chips and avoid clogging.

Usage recommendations

Use slower speeds and cutting fluid when drilling harder metals; for wood and softer materials, higher speeds are acceptable. Store bits in the provided case and inspect cutting edges before use; replace any bits that show significant wear or chipping to maintain drilling accuracy and safety.
