Value Collection SM0500450 Chucking Reamer 4.50mm Hss

Product Description

The VALUE COLLECTION SM0500450 is a 4-flute chucking reamer designed to bring bored or drilled holes to a precise finished diameter. Built from high-speed steel (HSS) with a bright, uncoated finish, it measures 4.50mm (0.1772 inches) in diameter and runs 4.5 inches overall with a 1.125-inch straight flute section. The straight-cylindrical shank seats securely in a drill chuck or collet. Right-hand cutting geometry produces clean, accurate holes in ferrous and non-ferrous metals. Machinists, toolroom technicians, and maintenance mechanics reach for this type of reamer when tolerance and surface finish matter more than a drill alone can deliver.

This reamer is suited for manual and CNC machine operations where a 4.50mm finished bore is required. Typical applications include sizing holes for dowel pins, bearing seats, and close-tolerance fastener fits in steel, cast iron, aluminum, and similar materials. The straight flute design works best in through-holes and performs reliably at moderate speeds with appropriate cutting fluid applied.

Key Features

• 4.50mm (0.1772 inches) reamer diameter for precise hole finishing
• High-speed steel (HSS) construction for durability in general machining
• Bright, uncoated finish suitable for use across common metals
• 4-flute straight configuration for clean, consistent material removal
• Right-hand cutting direction, compatible with standard machine rotation
• Straight-cylindrical shank for secure chuck or collet mounting

Compatibility

Designed as an OEM-style replacement or standard toolroom chucking reamer for machines accepting a straight-cylindrical shank in the 4.00mm to 5.00mm diameter range.

Installation Notes

Chucking reamers are installed by a machinist or toolroom technician into a drill press, lathe tailstock, or CNC spindle using a compatible chuck or collet. Power down and lock out the machine before changing tooling. Use cutting fluid appropriate to the workpiece material to extend tool life and improve surface finish. Do not use a reamer to remove more stock than manufacturer-recommended allowances for the diameter class — pre-drill or bore to the correct pre-ream size before finishing.
