Twist drill bit Irwin 10502407 — diameter 1.5 cm, 1 piece

Irwin 10502407 is a single twist drill bit with a 1.5 cm diameter designed for general-purpose drilling with handheld and bench drills. Manufactured to DIN 338 standards and featuring a reduced shank, this drill bit delivers precise through-holes and pilot holes in compatible materials. The 118° universal point shape and precision-ground cutting edges ensure fast drilling and a smooth finish, while the ground flute supports efficient chip evacuation.

Advantages

Ground-quality construction and precision grinding provide consistent concentricity and a clean hole surface. The reduced shank allows use in chucks with limited capacity without compromising rigidity. A universal 118° point shape makes the bit versatile across a variety of materials, and the ground flute geometry promotes rapid chip removal and stable drilling performance.

Suitable for

• Drilling through-holes and pilot holes in metals compatible with a high-speed steel twist drill
• General workshop and construction tasks performed with handheld or bench drills
• Applications requiring accurate hole diameter and clean finishes

Key specifications

• Diameter: 1.5 cm
• Quantity: 1 piece
• Standard: manufactured to DIN 338
• Point angle: 118° universal point
• Shank type: reduced shank
• Cutting: precision ground cutting edges
• Flute: ground flute for efficient chip removal

How to use

Secure the reduced shank in the drill chuck and ensure the drill is clamped firmly before operation. Mark the drilling position and, if needed, create a center punch to guide the bit. Start drilling at low speed to establish the hole, then increase speed appropriate to the material while applying steady pressure. Withdraw periodically to clear chips if drilling deep holes and use cutting fluid when working with metals to reduce heat and extend tool life.

Usage recommendations

Use the drill bit within recommended speed ranges for the material being drilled and apply cutting fluid when machining metals. Inspect the bit for wear or damage before use and replace if the cutting edges are dulled or the flute is clogged. Store the drill bit in a dry place to avoid corrosion.
