HSS-E Sport Weld Drill, 8mm Diameter, 40mm Working Length

Brief Overview

This 8mm HSS-E Sport weld drill is purpose-built for spot-weld reaming and precision drilling in thin-walled sheet metal applications. The compact 40mm working length and short overall profile make it ideal for automotive and light fabrication work where access to recessed weld points is critical. The multi-flute cutting geometry delivers clean, burr-free entry on aluminum, steel, brass, and copper plates. If your inventory requires broader size coverage, pair this with smaller weld drills and precision spot-weld drilling tools to serve diverse shop needs and weld diameters.

Key Features

• Material Grade: HSS-E (High Speed Steel Extra) – superior heat resistance and edge retention compared to standard HSS
• Optimized Geometry: Short, rigid design minimizes chatter and deflection when drilling thin-walled elements
• Multi-Flute Cutting Tip: Sharp, radiused cutting lips with proper relief angles for clean, burr-free entry on sheet metal
• Versatile Material Compatibility: Suitable for steel, brass, aluminum, zinc, copper, and plastic plates
• Compact Profile: 40mm working length fits tight spot-weld access points and recessed drilling areas
• Straight Cylindrical Shank: Fits standard chucks with minimal runout

Why Resellers Choose This Tool

High-Demand Application: Spot-weld removal and reaming is a recurring need in automotive repair, body shops, and fabrication—creating consistent customer demand and repeat orders.

Material Efficiency: The HSS-E grade extends tool life compared to standard drills, reducing your customers' per-hole cost and building loyalty for premium tooling purchases.

Bulk-Order Friendly: Single-unit packaging allows flexible inventory management and bundling with related drilling accessories. The 8mm size is the most commonly ordered diameter for automotive body work.

Thermal Resistance: HSS-E resists thermal cycling from repetitive friction drilling, crucial for production runs and high-volume spot-weld removal operations.

Why This Specification Matters

The 8mm diameter covers the most common weld perforation sizes in automotive bodywork. The 40mm working length provides sufficient reach for standard spot-weld drilling without excessive tool overhang, reducing vibration and improving hole quality. The HSS-E material resists thermal cycling from friction, crucial when drilling repetitively on production runs. The short overall profile fits into tight access areas where standard full-length drills cannot reach.
