HSS Straight Flute
Chucking Reamers
Dowel Pin Sizes
• Straight flute reamers are used in through
hole applications ONLY.
• High speed steel (HSS) provides good wear resistance
and can be used in general purpose applications
for both ferrous and nonferrous materials.
• Straight flute reamers are the most common and are
used in general purpose though-hole applications. They
are used for reaming holes without interrupted cuts.
• 45° chamfer for easy hole entry.
• Over/Under sizes all for a loose or tight fit.
• Dowel pin sizes help to make a perfect hole for dowel
pin insertion.

Spiral Flute Taper Pin Reamers
Left Hand Spiral/Right Hand Cut
• Reamers have a taper of ⁄ " to the foot and are
1 4
designed to ream holes for standard taper pins.
• Primarily for hand reaming.
• Best results when the hole to be reamed is drilled a few thousandths
smaller than the small diameter of the finish reamed hole.
• HSS gives good wear resistance in mild steel and nonferrous materials.

HSS Straight Flute
Chucking Reamers
Dowel Pin Sizes
• Straight flute reamers are used in through
hole applications ONLY.
• High speed steel (HSS) provides good wear resistance
and can be used in general purpose applications
for both ferrous and nonferrous materials.
• Straight flute reamers are the most common and are
used in general purpose though-hole applications. They
are used for reaming holes without interrupted cuts.
• 45° chamfer for easy hole entry.
• Over/Under sizes all for a loose or tight fit.
• Dowel pin sizes help to make a perfect hole for dowel
pin insertion.

Spiral Flute Taper Pin Reamers
Left Hand Spiral/Right Hand Cut
• Reamers have a taper of ⁄ " to the foot and are

designed to ream holes for standard taper pins.
• Primarily for hand reaming.
• Best results when the hole to be reamed is drilled a few thousandths
smaller than the small diameter of the finish reamed hole.
• HSS gives good wear resistance in mild steel and nonferrous materials.
